Ics Triplex T8461C Trusted TMR 24/48Vdc Digital Output Module

Description

• • Environmental Parameters
    • Temperature Adaptability: It operates stably within a temperature range of -5°C to 60°C, and can be stored in an environment with temperatures ranging from -25°C to 70°C without affecting its subsequent performance.
    • Humidity Tolerance: It can work and be stored normally in an environment with 5% – 95% relative humidity without condensation, adapting to the humidity changes of most industrial sites.
• Function Features
  • Triple Modular Redundancy Architecture: Each of the 40 output channels is built with a TMR architecture. Three independent circuits perform the same operations and vote on the results. This design achieves high fault tolerance and isolates any single-channel fault to ensure accurate and continuous output of control signals.
  • Independent Power Group Configuration: The 40 output channels are divided into 5 independent power groups, with 8 channels in each group. This structure prevents faults in one power group from spreading to others, which enhances the overall operational stability of the module and simplifies targeted maintenance work.
  • Comprehensive Diagnostic and Self-test Functions: The module conducts triplicated diagnostic tests on all parts, including measuring the current and voltage of each voting output channel, and detecting stuck-on and stuck-off faults. It also has a self-test function with an interval of 2 minutes to promptly find potential problems.
  • Automatic Channel Protection Mechanisms: Each channel is equipped with automatic overcurrent protection, so no external fuses are needed to avoid module damage caused by excessive current. It also has electronic latching short-circuit protection to quickly lock the fault state when a short-circuit occurs in the output channel.
  • Convenient Hot-swap and Status Monitoring: The module supports online hot replacement through dedicated adjacent slots or smart slots, which avoids system shutdown during maintenance and reduces downtime. Its front panel is equipped with LEDs for each channel to indicate output status and wiring faults, and module status LEDs to show health conditions and operational modes.
  • Precise Event Recording: The module supports on-board sequence of events reporting with 1ms resolution. It can accurately record the time of each output signal change event, providing reliable data support for subsequent system operation analysis and fault tracing.
• Application Scenarios
  • Oil and Gas Industry: It is applied in emergency shutdown systems and fire and gas protection systems for oil drilling platforms, long-distance pipelines and refining plants. It controls the start and stop of emergency shutdown valves and pumps. When abnormal conditions such as pipeline leakage and excessive pressure are detected, it sends out signals immediately to trigger protective measures and avoid explosion and leakage accidents.
  • Chemical Industry: It is integrated into the control systems of chemical reaction kettles, hazardous chemical storage tanks and transportation pipelines. It controls the operation of flow control valves and emergency cut-off devices. Its high reliability and redundant design ensure that the system can respond to abnormal chemical reactions in a timely manner and prevent dangerous incidents such as toxic gas leakage and violent reactions.
  • Power Generation Industry: It is used in safety control systems of thermal power, nuclear power and other power plants, especially in turbine protection circuits and boiler safety control links. It controls the switching of key auxiliary equipment and emergency shutdown mechanisms. When parameters such as equipment overspeed and abnormal water level occur, it can quickly output control signals to protect expensive power generation equipment from damage.
  • Marine Industry: It is deployed in the automation control systems of large ships, such as the control systems of ship power systems and navigation equipment. It adapts to the humid and vibrating marine environment and controls the start-stop and state adjustment of related marine equipment, ensuring the safe and stable operation of ships during navigation.
