Description

Key Technical Specifications

  • Connection & Communication Performance: The core function of this module is to establish a communication link between the Trusted controller chassis and up to four expander chassis, which effectively expands the I/O capacity of the entire control system. It supports Modbus TCP/IP and Modbus RTU communication protocols, enabling flexible and seamless integration with different types of automation systems. It is equipped with four 12-pin ODU connectors for connecting the expander chassis and a 96-way C-type connector for interfacing with the controller chassis.
  • Safety & Environmental Adaptability: It adopts a TMR triple modular redundancy architecture, so the system can still operate continuously even if individual components fail. It has passed certifications such as CE, UL and SIL 3, and is fully compliant with strict safety standards for industrial critical applications. The module uses a stainless steel enclosure with EMC shielding. It can work stably in an environment with a temperature of -40°C to +70°C and a non-condensing humidity of 5%-95%, and can resist the interference of harsh industrial environments.
  • Physical & Power Traits: The T8312 has a compact size, and the dimensions of its variant T8312-4 are 31.8mm×168mm×147mm, weighing about 0.6kg. It supports DIN rail or chassis mounting, which is convenient for integration into existing control system racks. It adopts 24V DC power supply, with a typical power consumption of 6W, and supports redundant power supply to ensure continuous operation of the equipment. In addition, it is equipped with built-in LED indicators to display the operating status in real time.

Field Application & Problem Solved

  • Oilfield Drilling Control System Expansion: In oilfield drilling operations, a large number of sensors and actuators need to be connected to monitor parameters such as drilling pressure and speed. The T8312 module can connect the main controller chassis with multiple expander chassis distributed near the drilling equipment. Its TMR redundancy design avoids signal interruption caused by module failure, ensures the continuous collection and transmission of drilling data, and solves the problem of insufficient I/O interfaces of the single controller chassis, which is crucial to maintaining the safety and efficiency of drilling operations.
  • Chemical Plant Safety Control System Upgrade: In chemical plants, the traditional control system often faces the dilemma that the I/O capacity is difficult to meet the needs of newly added monitoring points during expansion. The T8312 can be seamlessly integrated into the original Trusted control system. By connecting the expander chassis, it can easily add new I/O modules to connect the newly added temperature, pressure and toxic gas concentration sensors. Its integrated fault detection function can promptly alarm potential communication failures, helping staff deal with problems in time and avoiding safety accidents caused by delayed data transmission.

Installation & Maintenance Pitfalls (Expert Tips)

  1. Connector Connection Check: When connecting the 96-way C-type connector and the 12-pin ODU connector, ensure that the connection is tight. The module is equipped with a release button for disconnection, and violent pulling should be avoided during disassembly to prevent damage to the connector pins. After installation, conduct a communication test to confirm that the signal between the controller chassis and the expander chassis is unobstructed.
  2. Redundant Power Configuration: Since the module supports redundant power supply, when configuring the power supply, two independent 24V DC power sources should be connected. Avoid using a single power supply, as this will lose the fault-tolerant advantage of redundant power supply. Regularly check the power supply voltage to ensure it is within the stable operating range to prevent module malfunctions due to voltage fluctuations.
  3. Regular Diagnostic Monitoring: Make use of the module’s integrated diagnostic function. During daily maintenance, pay close attention to the LED status indicators and fault alarm signals. Once an abnormal signal is found, trace the cause of the fault immediately. At the same time, keep the module’s enclosure clean. Although it has good corrosion resistance, long-term accumulation of chemical dust may affect the heat dissipation and shielding effect, so regular cleaning is required.
