TRICONEX 8310N2

I. Overview

TRICONEX 8310N2 is a high-performance safety control module and an important component in the Safety Instrumented System (SIS). It is specially designed for high-risk industrial scenarios and plays a key role in industrial production safety protection with its top-level safety performance and stable control capabilities.

In the oil and gas industry, it can monitor key parameters such as pressure and temperature of drilling platforms and oil pipelines in real-time. Once an abnormality occurs, it can quickly trigger safety interlocks, such as closing valves and stopping equipment operation, to prevent major accidents like leaks and explosions. In the chemical industry, it accurately controls the operating status of core equipment such as reactors and distillation towers, ensuring the safe and stable progress of chemical reaction processes. In addition, it is also widely used in industries with extremely high safety requirements such as nuclear industry, electric power, and rail transit. Through reliable safety control logic, it minimizes safety risks in industrial production and provides a solid guarantee for personnel safety and stable operation of equipment.

II. Technical Parameters

Power parameters: Supports 24V DC power supply, with overvoltage and undervoltage protection functions. It can work stably when the power supply voltage fluctuates, ensuring the continuous operation of the module. The power consumption is about 20W, which is low in energy consumption and meets industrial energy-saving needs.

Processing capability: Equipped with a high-performance 32-bit processor, it has a fast computing speed and can efficiently process complex safety control logic and a large amount of real-time data. It supports multiple programming languages such as ladder diagram, Function Block Diagram (FBD), and Structured Text (ST), facilitating engineers to develop and debug programs according to actual needs.

Input and output interfaces: Equipped with 24 digital input and 16 digital output interfaces. The digital input has a short response time and can quickly capture signal changes of devices such as sensors and limit switches; the digital output can stably drive actuators such as relays and solenoid valves, ensuring the accurate execution of control commands.

Communication capability: Supports mainstream industrial communication protocols such as Modbus TCP/IP and EtherNet/IP, enabling high-speed data interaction with upper monitoring systems, HMI, and other intelligent devices. The communication interface adopts an optoelectronic isolation design, which has strong anti-electromagnetic interference ability, ensuring communication stability in complex industrial environments.

Environmental adaptability: The operating temperature range is -40℃ to 70℃, allowing normal operation in extremely high and low temperature environments; the relative humidity is 5% - 95% (no condensation), which can adapt to humid environments. The protection level reaches IP20, suitable for installation in control cabinets, effectively preventing dust intrusion.
Safety certification: Certified by SIL3 (Safety Integrity Level 3), compliant with international safety standards such as IEC 61508 and IEC 61511. Its safety performance reaches a high industry standard, meeting the strict safety requirements of high-risk industrial scenarios.

III. Functional Features

Triple Modular Redundancy (TMR) technology: Adopts TRICONEX's iconic TMR technology, consisting of three independent and synchronously operating processing channels. Each channel executes the same program and performs real-time data comparison, ensuring the output of correct control signals through a hardware voting mechanism. Even if a single channel fails, the system can still maintain normal operation relying on the other two channels, completely eliminating the risk of single-point failure and greatly improving the reliability and safety of the module.

High-speed safety interlock response: It has an extremely short response time to input signals, can identify abnormal states within milliseconds, and quickly output control commands according to preset safety logic. In emergency situations, such as detecting dangerous conditions like overpressure and overtemperature, it can instantly trigger safety actions such as emergency shutdown and cutting off energy supply, minimizing accident losses.

Comprehensive self-diagnosis and alarm functions: Equipped with a complete self-diagnosis mechanism, which can real-time monitor the integrity of the module's internal hardware (such as processor, memory, input and output channels), program operation status, and externally connected equipment. When a fault is detected, it immediately sends an alarm signal through indicator lights and communication interfaces, and records the fault code, facilitating maintenance personnel to quickly locate the fault point and shorten the fault troubleshooting time.

Online configuration and maintenance: Supports online programming, parameter modification, and program download without interrupting system operation, reducing production downtime caused by maintenance. Engineers can remotely configure and monitor the module through dedicated software, improving the convenience and efficiency of system maintenance.

Strong compatibility and expandability: It has excellent compatibility with other modules of the TRICONEX series (such as input/output expansion modules and communication modules) and can be easily integrated into existing safety instrumented systems. At the same time, it supports increasing the number of input/output points and communication interfaces through expansion racks, meeting the control needs after the expansion of industrial production scale or process upgrading.

IV. Common Faults and Solutions

Communication connection failure
Causes of failure: Poor contact or damage of communication cables; incorrect setting of network parameters such as IP address and subnet mask; hardware failure of the communication interface.
Solutions: Check the connection of communication cables, re-plug the connectors or replace with new cables; check and reconfigure network parameters to ensure they are in the same network segment as the upper system and the parameters match; if the interface hardware is faulty, replace the communication interface module or contact professional technical personnel for maintenance.
Loss of input signal
Causes of failure: Open circuit or short circuit of the input line; abnormal power supply of the sensor leading to no signal output; damage of the input channel.

Solutions: Use a multimeter to detect the on-off and voltage of the input line, and repair the broken or short-circuited points; check the sensor power supply to ensure normal power supply, and replace the faulty sensor; test by replacing with a normal module, and if it is determined that the input channel is damaged, replace the module.

Unable to execute output command
Causes of failure: Short circuit of the output line causes the module to start the protection mechanism; failure of the actuator (such as relay, solenoid valve); damage of the output channel.
Solutions: Check the output line to eliminate the short-circuit fault and restore the output function of the module; detect the working status of the actuator and replace the faulty actuator; if the output channel is damaged, replace the module or repair the corresponding parts.
Abnormal flashing of the module running indicator
Causes of failure: Unstable power supply voltage or beyond the normal range; excessive internal temperature of the module; program operation error or memory failure.
Solutions: Detect the power supply voltage to ensure it is stable at 24V DC; check the heat dissipation of the module, clean the dust in the heat dissipation holes, and improve ventilation conditions; read the fault information through programming software, re-download the program or repair the memory fault, and if it is a hardware problem, contact the manufacturer to replace the module.
