Triconex 3635R Normally Closed Relay Output Module

Description

• Functional Features
  • Independent Normally Closed Relay Output: With 32 non-common normally closed relay output points, each point operates independently without mutual interference. This design ensures that the failure of a single output channel will not affect the operation of other channels, enhancing the stability of the entire module’s output.
  • Integration with Triple Modular Redundant Architecture: It is fully integrated into the Triconex system’s triple modular redundant structure. The module’s internal microprocessor provides data support for output data voting. It checks the validity of the output state through the feedback loop voltage at the output terminal and diagnoses problems in on-site lines, which is consistent with the Triconex system’s overall fault diagnosis and fault-tolerant operation mechanism.
  • Online Maintenance Compatibility: It supports online module installation and maintenance. During maintenance, the on-site wiring does not need to be disconnected, and the module can be replaced without shutting down the entire control process. This maintains the continuous operation of the industrial production process and reduces downtime losses.
  • Strong Environmental Adaptability: The module is designed to withstand harsh industrial environments. Its structural design and component selection can resist the impact of factors such as electromagnetic interference and voltage fluctuations on the module’s operation, ensuring stable relay action and output signal accuracy in complex on-site conditions.
• Application Scenarios
  • Oil and Gas Industry: It is applied in emergency shutdown systems and fire and gas protection systems of offshore oil platforms and onshore oil transmission stations. It controls the normally closed safety valves and emergency cut-off valves. When abnormal conditions such as gas leakage occur, it can quickly trigger the relay to act and close the relevant valves to prevent leakage expansion.
  • Petrochemical Industry: It is used in the safety control systems of chemical reactors and hazardous chemical storage areas. It is connected to the on-site alarm and interlock mechanisms. When the temperature, pressure, or other parameters of the reactor exceed the set thresholds, it can immediately drive the relay to execute shutdown or isolation commands to avoid violent chemical reactions or toxic substance leakage.
  • Power Generation Industry: It is integrated into the boiler protection systems and steam turbine safety control systems of thermal power plants and nuclear power plants. It controls the normally closed switches of auxiliary equipment such as fuel supply pipelines and cooling systems. When equipment malfunctions are detected, it can quickly cut off the relevant equipment circuits through relay action to prevent equipment damage and large-scale power outages.
  • Metallurgical Industry: It is used in the safety interlock systems of steelmaking blast furnaces and continuous casting equipment. It controls the relay switches of water supply, air supply, and other key auxiliary systems. When abnormal temperature or pressure occurs in the smelting process, it can immediately cut off the supply of relevant media to protect the smelting equipment from damage and ensure the safety of operators.
