Triconex 3626X Supervised Triple Modular Redundant Digital Output Module

Description

• • Environmental Parameters
    • Operating Temperature Range: -40°C to +70°C
    • Storage Temperature Range: -40°C to +85°C
    • Relative Humidity Tolerance: 5% – 95% under non-condensing conditions
• Functional Features:
  • Triple Modular Redundancy Architecture: The module operates with three independent and parallel circuit units that perform the same control logic simultaneously. It uses 2oo3 majority voting logic. When one circuit unit fails, the other two normal units can still ensure accurate output of control signals, which fundamentally eliminates single-point failure risks and improves system reliability.
  • Comprehensive Online Diagnostic Capabilities: It continuously monitors the working status of each output channel, power supply stability, and isolation circuit integrity in real time. Once an abnormal situation such as overcurrent, undervoltage, or poor contact occurs, it can quickly locate the faulty part and send out fault alarm signals to the controller, providing strong support for maintenance personnel to carry out targeted maintenance.
  • Optical Isolation Anti-Interference Design: It adopts optical isolation technology to isolate the internal control circuit from the external field load. This design can effectively block electromagnetic interference and voltage surges from the industrial field from entering the module’s core circuit, ensuring the stability and accuracy of signal output even in harsh electromagnetic environments.
  • Hot Standby and Hot Swap Support: The module supports hot standby function and can achieve seamless switching with the standby module when a fault occurs. It also supports hot swap operation. Maintenance personnel can disassemble and replace the faulty module without shutting down the entire safety system, which minimizes system downtime and ensures continuous industrial production.
  • Seamless System Compatibility: It can be perfectly integrated with Triconex Trident series safety controllers and other matching modules. The plug-and-play design enables quick configuration and commissioning after installation, reducing the difficulty and time cost of system integration.
• Application Scenarios:
  • Oil and Gas Industry: It is widely used in safety interlock systems and emergency shutdown systems of offshore oil platforms, onshore refineries, and long-distance oil and gas pipelines. It is mainly used to control emergency cut-off valves and fire-fighting equipment. When gas leakage or pressure exceeds the limit, it can immediately trigger related equipment to act to avoid explosion and fire accidents.
  • Nuclear Power and Thermal Power Industry: It is applied to the safety protection systems of nuclear power plants and thermal power plants. It participates in the control of boiler protection systems, steam turbine emergency shutdown mechanisms, and nuclear reactor auxiliary equipment. It can quickly respond to abnormal parameters and issue shutdown or adjustment signals to prevent major safety accidents such as equipment explosion and core leakage.
  • Petrochemical Industry: It is used in the safety control links of chemical reactors, distillation towers, and hazardous chemical storage tanks. When the reaction temperature, pressure, or concentration of harmful substances in the production process exceeds the set threshold, it can drive the discharge valve and isolation valve to act, avoiding the leakage of toxic and harmful substances and the occurrence of violent chemical reactions.
  • Pharmaceutical Industry: It is used in the safety control systems of sterile pharmaceutical production lines and hazardous drug processing workshops. It controls the start and stop of mixing equipment, conveying pipelines, and sterilization equipment. It complies with GMP and FDA regulatory requirements and ensures the safety of the pharmaceutical production process and the stability of product quality.
  • Railway Transportation Industry: It is integrated into the signal control system of railway lines. It is used to control the switching of turnout and the on-off of signal lights. It ensures the accuracy and timeliness of signal transmission, avoids collision accidents between trains, and improves the safety of railway operation.
