Triconex 3636T Digital Normally Open Relay Output Module

Description

• Functional Features
  • Signal Voting and Reliable Relay Driving: The module collects signals from the main processor via three channels, and the voting mechanism for these signals ensures the accuracy of the control instructions. It drives 32 independent relays based on the voted data, enabling precise control of various external on-site equipment without mutual interference between each output point.
  • Independent Relay Operation Verification: Each output point is equipped with a dedicated loopback circuit. This circuit can verify the operation of each relay switch independently without relying on the presence of a load, eliminating the blind spot of fault detection caused by load absence and ensuring that every relay’s action is effective and detectable.
  • Continuous Diagnostic and Fault Alarm: It carries out continuous diagnostic tests on its own operational status during operation. Any diagnostic failure will activate the module’s fault indicator immediately, and this fault signal will further trigger the chassis alarm of the entire system, allowing maintenance personnel to quickly locate and handle problems.
  • Hot-Spare Support and Hot-Swappable Design: The module supports hot-spare module configurations, which enables seamless switching to the standby module when a fault occurs in the working module. Its 6U VME slot design supports hot-swapping, minimizing downtime during maintenance and replacement and ensuring the continuity of industrial production processes.
  • Strong Isolation Protection: The robust channel-to-channel and channel-to-ground isolation design prevents electrical interference between different output channels and between channels and the ground. This protection mechanism effectively avoids misoperation of the module caused by external electrical interference and ensures the stability of output signals.
• Application Scenarios
  • Oil and Gas Industry: It is applied to the annunciator panel systems of onshore oil refineries and offshore drilling platforms. It connects to auxiliary equipment such as small-scale solenoid valves and warning buzzers in oil and gas transmission pipelines. When the system detects minor pressure fluctuations or slight leakage, it can drive the relay to activate the warning devices and adjust the small solenoid valves to maintain the stability of the transmission process.
  • Petrochemical Industry: It is used in the auxiliary control systems of chemical distillation towers and storage tanks for general chemicals. It is responsible for controlling non-critical on-site alarms and small flow control valves. When production parameters deviate slightly from the standard range, it triggers the corresponding relay to start the alarm and fine-tune the valves, avoiding unnecessary production interruptions.
  • Power Generation Industry: It is integrated into the auxiliary systems of thermal power plants, such as the control systems of boiler auxiliary fans and cooling water circulation auxiliary equipment. It controls the start and stop of these non-critical auxiliary devices. When minor malfunctions are detected in the equipment, it can quickly cut off the power supply of the faulty equipment through relay action without affecting the operation of the main power generation system.
  • Water Treatment Industry: It is deployed in the control systems of urban sewage treatment plants and industrial wastewater purification facilities. It controls the operation of non-critical equipment such as small dosing pumps and water level warning lights. According to real-time water quality and water level data, it drives relays to adjust the working state of the dosing pumps and activates warning lights when the water level exceeds the set range.
  • Pharmaceutical Industry: It is used in the auxiliary control links of pharmaceutical production lines, such as the control of material conveying belt auxiliary mechanisms and clean area air circulation small fans. It meets the strict safety and cleanliness requirements of the pharmaceutical industry. It reliably controls these non-critical auxiliary equipment to ensure the smooth progress of pharmaceutical production processes and the stability of product quality.
