(II) Electrical and Environmental Parameters

1. Power Supply and Power Consumption

• Power Supply Method: Powered via the backplane of the Mark VIe standard I/O rack (24V DC redundant power supply, provided by KJ2001 series power modules). The rated power consumption of a single module is ≤8W (when 8 channels are at full-load output);
• Power Supply Protection: Equipped with reverse polarity protection (no damage when input voltage is reversed), overcurrent protection (automatic current limiting when total overcurrent ≤1A), and undervoltage protection (output maintains "last value" state when power supply voltage ＜18V DC);
• Isolation Performance:
• Inter-channel Isolation: 2500V AC (withstand voltage for 1 minute), preventing signal crosstalk between channels;
• Channel-to-Backplane Isolation: 1500V AC (withstand voltage for 1 minute), common-mode interference resistance of ±250V DC, complying with the IEC 61131-2 industrial isolation standard.

2. Environmental Adaptability

• Operating Environment: Temperature 0℃-60℃ (no derating), storage temperature -40℃-85℃, relative humidity 5%-95% RH (no condensation);
• Protection Class: The module itself has an IP20 protection class (must be installed in a Mark VIe standard control cabinet). The PCB board is treated with a moisture-proof coating, adapting to dusty and high-humidity environments in industrial workshops;
• Electromagnetic Compatibility: Passed IEC 61000-4-2 (±8kV contact discharge), IEC 61000-4-4 (±2kV electrical fast transient), and IEC 61000-4-6 (10V/m radio frequency radiation) tests, resisting electromagnetic interference generated by frequency converters and high-power motors.

(III) Communication and System Compatibility Parameters

1. Communication Interfaces and Redundancy

III. Functional Features

(I) High-Density and High-Precision Output, Simplifying Control Architecture

• 4-20mA signals to drive the feedwater control valve (controlling boiler water level), desuperheating control valve (controlling steam temperature), air supply control valve (controlling furnace negative pressure), and induced draft control valve (controlling flue gas emission);

(II) Full Isolation and Anti-Interference Design, Ensuring Signal Reliability

(III) Flexible Configuration and Fail-Safe, Adapting to Diverse Scenarios

• Signal Type Switching: Any channel can be configured as current or voltage output via software. It can adapt to different actuators (e.g., 4-20mA control valves and 0-10V frequency converters) without replacing hardware, reducing spare parts inventory;
• Fail-Safe Value Setting: Supports customizing the output value when a channel fault occurs (e.g., power failure, communication interruption) (e.g., 4mA for valve closing, 12mA for maintaining opening). In the control of power plant steam pipelines, 4mA is output when power is off to close the control valve, avoiding the risk of steam leakage;
• Remote Calibration: Zero-point and full-scale calibration of each channel can be performed remotely via ControlST software, without on-site module disassembly. The calibration error is ≤±0.01% FS, reducing downtime for maintenance.

(IV) Redundancy and Diagnostics, Reducing Operation and Maintenance Costs

IV. Application Fields

(I) Power Industry: Auxiliary Control of Boilers and Steam Turbines

• Boiler Water Level Regulation: The module outputs 4-20mA signals to drive the feedwater control valve, realizing closed-loop control based on the feedback from the boiler water level transmitter (4-20mA). The water level control accuracy is ±5mm, avoiding steam entrainment due to excessively high water levels or dry boiling due to excessively low water levels;
• Steam Turbine Lubricating Oil Pressure Control: Outputs 0-10V signals to control the speed of the lubricating oil pump frequency converter, stabilizing the oil pressure at 0.25MPa±0.02MPa to ensure the lubrication of steam turbine bearings. The module's temperature drift characteristic ensures no significant oil pressure fluctuation when the oil temperature changes.

(II) Petrochemical Industry: Control of Pipelines and Reactors

• Crude Oil Pipeline Pressure Control: The module outputs 4-20mA signals to drive pipeline pressure control valves, realizing stable pressure control (0.8MPa±0.03MPa) based on the feedback from pressure transmitters, avoiding pipeline rupture due to excessively high pressure or transportation interruption due to excessively low pressure;

(III) Metallurgical Industry: Control of Rolling Mills and Blast Furnaces

• Rolling Mill Hydraulic Roll Gap Control: The module outputs 4-20mA signals to drive hydraulic servo valves, controlling the roll gap of the rolling mill's work rolls. The roll gap control accuracy is ±0.01mm, meeting the needs of thin strip steel rolling. The 16-bit resolution ensures accurate execution of small roll gap adjustments;
• Air-Fuel Ratio Control of Blast Furnace Hot Blast Stoves: Outputs 4-20mA signals to drive gas control valves and combustion air control valves respectively, realizing accurate control of the air-fuel ratio at 1:10±0.1, ensuring full fuel combustion and stabilizing the hot blast temperature at 1200℃±10℃.

(IV) Municipal and Light Industry: Water Treatment and Production Line Control

• Aeration Control in Sewage Treatment: The module outputs 4-20mA signals to drive aeration valves, adjusting the aeration volume based on the feedback from a dissolved oxygen transmitter (0-20mg/L). The dissolved oxygen control accuracy is ±0.5mg/L, reducing aeration energy consumption;

V. Selection and Engineering Implementation Recommendations

(I) Selection Criteria

• Channel Quantity Matching: This module is preferred when the single system requires 8 or fewer analog output channels; for more than 8 channels, multiple modules can be cascaded, or the 16-channel version IS210WSVOH2AE can be selected;
• Signal Type Requirements: It is best suited for scenarios requiring simultaneous output of 4-20mA and 0-10V signals (software-switchable); for pure current or pure voltage output scenarios, dedicated modules (e.g., IS210WSVIH1AE current input module) can be selected;
• Accuracy and Environment: Applicable to non-hazardous areas with control accuracy requirements ≤±0.1% FS and ambient temperature of 0℃-60℃; for high-temperature (＞60℃) or explosion-proof scenarios, upgraded versions (e.g., IS210WSVOH1AE-EX explosion-proof type) must be selected.

(II) Peripheral Configuration Recommendations

• Actuator Adaptation: For 4-20mA output, the GE Fisher DVC6200 intelligent valve positioner (load impedance 250Ω) is preferred; for 0-10V output, it is adapted to the Siemens MM440 frequency converter (input impedance 10kΩ);
• Power Supply Configuration: Must be matched with Mark VIe standard redundant power modules (e.g., IS200PWRCH1A, 24V DC/10A) to ensure stable power supply; for non-Mark VIe systems, compatibility can be achieved through protocol converters (e.g., MOXA MGate), but it is recommended to use it in the Mark VIe system first to ensure complete functionality;
• Wiring Specifications: Twisted shielded cables (cross-sectional area 0.75mm²) should be used for analog output cables; the shield layer should be grounded at one end (ground resistance ≤1Ω); the distance from power cables should be ≥300mm to avoid electromagnetic interference; the cable length should be ≤500m (for 4-20mA) and ≤100m (for 0-10V) to avoid signal attenuation.

(III) Installation and Commissioning Notes

• Installation Specifications: The module must be installed in a Mark VIe standard I/O cabinet (e.g., IC698CAB100), with a distance of ≥200mm from frequency converters and contactors to avoid heat dissipation impact; the rack ground resistance should be ≤4Ω to ensure isolation effect;
• Parameter Configuration: Configure the signal type (current/voltage) of each channel, output range (e.g., 4-20mA corresponding to 0-100% valve position), and fail-safe value via ControlST software; the module must be preheated for 30 minutes before calibration to ensure stable temperature drift;
• Commissioning and Verification:
• Accuracy Test: Input digital commands (0%, 50%, 100%) and measure the output value with a standard ammeter/voltmeter; the error should be ≤±0.05% FS;
• Fault Test: Simulate a channel short circuit (connect a 2Ω resistor) to confirm that the module triggers short-circuit protection and reports the fault; simulate a power failure to check if the output switches to the preset safe value;
• Redundancy Test: Under rack-level redundancy configuration, disconnect the power supply of the main rack and confirm that the module in the standby rack takes over the output within 1ms without signal interruption.
