In the model, "IC698" identifies the industrial control hardware series it belongs to, "PSA" stands for Power Supply, and "100E" precisely defines its output power level, input voltage type, and hardware configuration version.

This product is specifically designed for fields with strict requirements on power supply stability, such as medium and large-sized industrial automation control systems, process control scenarios, and high-end manufacturing equipment. Its core function is to convert the AC input voltage on the industrial site into a stable DC output voltage required by controllers and various modules, providing a reliable "energy core" for the entire control system. It is compatible with all specifications of GE 698 series controller chassis and supports various ControlLogix series modules including processor modules, I/O modules, and communication modules. It is widely used in key industrial fields such as power generation control, petrochemical process control, metallurgical production line control, rail transit signal control, and semiconductor manufacturing equipment. It can operate continuously and stably in complex industrial on-site environments, effectively resisting common power supply risks such as voltage fluctuations and electromagnetic interference.

GE IC698PSA100E takes "highly stable output, wide-range input adaptation, comprehensive safety protection, and harsh environment resistance" as its core value proposition. It adopts an advanced switching power supply topology, with an output power of up to 100W, capable of stably providing a 24V DC standard industrial control power supply. It supports a wide AC input range of 85~264V, adapting to industrial grid voltages in different regions around the world. It is equipped with multiple safety protection functions such as overvoltage protection, undervoltage protection, overcurrent protection, short-circuit protection, and overtemperature protection, which can effectively prevent damage to downstream control modules caused by power supply failures.

III. Functional Features

1. Wide-Range Input + Stable Output, Adapting to Power Supply Needs of Multiple Scenarios

GE IC698PSA100E adopts a wide-range AC input design, with an input voltage range of 85~264V AC and a frequency compatibility of 47~63Hz. It can be directly adapted to the grid voltages of major industrial regions around the world without the need for additional voltage conversion devices, greatly improving the product's versatility. For example, in overseas factories of multinational enterprises (such as 230V AC in Europe and 110V AC in North America), this power supply module can be directly connected to the local power grid to provide stable power supply for the control system, avoiding equipment damage or abnormal operation caused by voltage mismatch. At the same time, its power factor is ≥0.95 (above 50% load), which can effectively reduce harmonic pollution to the power grid and comply with green industrial power consumption standards.

In terms of output stability, the module adopts advanced PWM (Pulse Width Modulation) technology and a high-precision feedback regulation circuit to achieve a rated output of 24V DC. The voltage adjustment range supports fine adjustment of 22.8~25.2V DC, which can be accurately adapted to the power supply needs of downstream modules. The load regulation rate is ≤±0.5% (when the load changes between 20%~100%), and the line regulation rate is ≤±0.1% (when the input voltage changes between 85~264V AC). Even in scenarios where the industrial grid voltage fluctuates or the load of downstream modules changes drastically (such as when multiple I/O modules start simultaneously), the output voltage fluctuation can still be controlled within a very small range. For example, in a metallurgical production line, when multiple motor control modules start simultaneously, causing the load to jump from 30% to 100%, the output voltage only fluctuates by ≤0.12V, ensuring the stable operation of core equipment such as processor modules and communication modules. In addition, the module's output ripple and noise are ≤100mVp-p, which can effectively avoid the interference of power supply noise on precision equipment such as analog acquisition modules and improve the measurement accuracy of the control system.

2. Multiple Safety Protections, Ensuring Safe Operation of the System

GE IC698PSA100E has five core built-in protection functions: "overvoltage protection, undervoltage protection, overcurrent protection, short-circuit protection, and overtemperature protection", forming a comprehensive safety protection system. It can not only protect the power supply module itself from fault damage but also provide reliable power supply guarantee for downstream control modules. The Overvoltage Protection (OVP) is set at 26.5~28.5V DC. When the output voltage rises abnormally due to circuit faults, the module immediately cuts off the output or enters the constant voltage protection mode to prevent downstream modules from being burned due to overvoltage. The Overcurrent Protection (OCP) adopts a constant current mode design. When the output current exceeds 4.5~5.5A, the module maintains a constant current output, which not only prevents the module from being damaged by excessive current but also provides peak current support (such as 6A peak current for 10s) for the startup of downstream modules.

Short-Circuit Protection (SCP) is a key safety feature of the module. When a short circuit occurs at the output end (such as positive and negative poles overlapping due to cable damage), the module immediately enters the protection state, and the output current quickly drops to a safe range. After the short-circuit fault is eliminated, the output is automatically restored without manual restart, greatly improving the system's fault tolerance. The Overtemperature Protection (OTP) monitors the internal temperature of the module in real-time through a built-in temperature sensor. When the temperature exceeds 85℃±5℃, the module cuts off the output and automatically recovers when the temperature drops below 70℃, effectively avoiding accelerated aging or even burning of the module due to poor heat dissipation or high ambient temperature. The Undervoltage Protection (UVP) is triggered when the input voltage is lower than 75V AC, preventing the module from overloading at low voltage and extending the module's service life. In addition, the input end of the module has a surge protection capability of ±2kV line-to-line and ±4kV line-to-ground, which can resist common grid surge impacts in industrial sites, such as overvoltage caused by lightning induction and transformer switching.

3. Industrial-Grade Environmental Adaptability, Withstanding Challenges of Complex Working Conditions

Through structural optimization, material selection, and circuit design, GE IC698PSA100E has excellent industrial-grade environmental adaptability and can cope with complex working conditions such as high temperature, low temperature, vibration, and electromagnetic interference. In terms of temperature adaptability, the module has an operating temperature range of -20℃~70℃, and adopts capacitors, semiconductor devices with a wide temperature range, and an aluminum alloy shell with excellent thermal conductivity. Even in cold outdoor control cabinets (such as substations in northern winter) or high-temperature metallurgical workshops (with an ambient temperature of above 50℃), it can still operate stably. When starting at a low temperature of -20℃, the module can reach the rated output within 3 seconds without startup delay or output fluctuation.

In terms of mechanical performance, the module adopts a reinforced PCB design and anti-vibration pin layout. Its vibration resistance reaches 5g (10~500Hz, tri-axial), and its shock resistance reaches 15g (11ms half-sine wave), which can adapt to continuous vibration generated by the operation of industrial motors and pumps, or shock damage during transportation and installation. In scenarios with severe vibration such as rail transit signal control cabinets and ship power control systems, the module can still maintain stable power supply performance. In terms of electromagnetic compatibility, the module has passed EN 55032 Class B and FCC Part 15 Class B electromagnetic emission certifications, as well as multiple electromagnetic immunity certifications. In environments with strong electromagnetic interference such as industrial frequency converters and high-voltage equipment, it will not radiate interference to affect other equipment, nor will it suffer from output fluctuations or faults caused by external interference, ensuring the stability of the control system. For example, in a petrochemical workshop, when the module operates near a high-power frequency converter, the output ripple can still be controlled within 50mVp-p without abnormal alarms.

4. Hot-Swappable Design + Intelligent Diagnosis, Improving Operation and Maintenance Efficiency

GE IC698PSA100E adopts a dedicated power supply slot design compatible with GE 698 series controller chassis and supports the hot-swapping function. That is, without shutting down the control system, the module can be directly inserted or removed for replacement or maintenance, greatly shortening the fault handling time. For example, in a power generation control scenario, if the power supply module fails suddenly, maintenance personnel can quickly replace it with a standby module without interrupting the control of the generator set, avoiding the shutdown of the generator set due to power supply interruption. A single fault handling can reduce economic losses of hundreds of thousands of yuan. The module adopts gold-plated pins, with a plug-in life of ≥100 times, ensuring contact reliability.

The module is equipped with comprehensive intelligent diagnosis and status indication functions, and intuitively feeds back the operating status through the two-color LED indicator on the front panel: steady green indicates normal operation of the module; steady red indicates an overvoltage, overcurrent, or overtemperature fault; blinking red indicates an input undervoltage fault. At the same time, the module provides 1 dry contact alarm output interface, which can upload fault signals to the upper computer monitoring system (such as GE Proficy iFIX) to realize remote monitoring and alarming of faults. Maintenance personnel can quickly locate the fault type through the indicator light or monitoring system without using professional instruments for detection, greatly improving the operation and maintenance efficiency. For example, when the monitoring system receives a dry contact alarm signal, combined with the fault code displayed on the upper computer, it can immediately determine whether it is input undervoltage or output overcurrent, and take targeted troubleshooting measures. In addition, the module supports the Sense remote voltage compensation function. When the output cable is long and causes line loss, the Sense+ and Sense- terminals can be connected to the load end to automatically compensate for the line loss voltage, ensuring that the load end obtains an accurate 24V DC voltage.

5. Flexible Installation + Efficient Heat Dissipation, Adapting to Diverse Deployment Scenarios

GE IC698PSA100E provides two flexible installation methods. It is not only compatible with the dedicated power supply slots of GE 698 series controller chassis and can be directly inserted into the chassis for integrated deployment with other modules to save cabinet space, but also supports DIN rail installation (requires matching rail brackets), which is suitable for deployment scenarios such as independent power control cabinets or non-GE standard chassis, such as power supply upgrades for third-party industrial control cabinets. The module is compact in size (100mm×50mm×120mm) and weighs only 300g, making it easy to install even in narrow control cabinets.

In terms of heat dissipation design, the module adopts a hybrid heat dissipation method of "natural heat dissipation + forced convection assistance". The aluminum alloy shell serves both as structural support and heat dissipation. The internal power devices are closely attached to the shell through thermal pads to quickly dissipate heat. When operating at full load and with an ambient temperature ≤50℃, natural heat dissipation can meet the needs; when the ambient temperature exceeds 50℃ or the module is installed in a closed cabinet, forced convection can be formed through cabinet fans to ensure that the internal temperature of the module does not exceed 85℃. The module's heat dissipation air duct is reasonably designed with no heat dissipation dead corners, which can avoid local overheating even when multiple modules are densely deployed. For example, in a control cabinet fully equipped with 4 IC698PSA100E modules, after turning on the cabinet fan, the temperature of each module can be controlled below 70℃ to maintain stable operation.
