TRICONEX 3564 single-channel digital input module

TRICONEX 3564 is a single-channel digital input module specially designed for TRICONEX Safety Instrumented Systems (SIS), used to receive and convert digital signals from field devices to achieve effective monitoring and protection of hazardous processes. The detailed introduction is as follows:

• High Reliability: Adopts triple redundancy design and self-diagnosis function. Even if one or two channels fail, the module can still operate normally. It can detect on/off faults within 0.5 seconds to ensure reliable signal transmission.

• High Safety: Complies with IEC 61508 and SIL 3 standards, effectively ensuring system safety.

• Optical Isolation: The input and output circuits are electrically isolated from each other to prevent electrical noise from interfering with signals. The isolation voltage between input points reaches 1500VDC, featuring strong anti-interference capability.

• Modular Design: Easy to install and maintain, supporting online replacement without shutdown, which reduces downtime and improves production efficiency.

• Strong Compatibility: Maintains good compatibility with TRICONEX series products, enabling convenient integration into TRICONEX safety instrumented systems.

• Flexible Configuration: Supports multiple input types and signal voltages, adapting to different external devices or signal sources.

• 
  

• Input Voltage: 24VDC, with a rated operating voltage range of 15–30VDC and a maximum of 36VDC.

• Maximum Current: 2A.

• Number of Channels: Single channel, providing 64 shared input points.

• Input Signal Type: Digital signals.

• Sampling Period: 100 milliseconds.

• Communication Interfaces: Supports Ethernet, RS-232, RS-485, etc., and is also equipped with a Triconex bus interface.

• Operating Temperature Range: -85°C to 40°C.

• Oil and Gas Industry: Used for monitoring and controlling key equipment such as pipelines, storage tanks, compressors, and pump stations. It real-time acquires equipment operation status signals (e.g., switch status) to ensure the safety of production, storage, and transportation processes, and promptly triggers corresponding protection mechanisms in case of abnormalities.

• Chemical Industry: Applied in process monitoring and safety interlock systems to monitor equipment such as reactors, separators, and pipelines. It receives signals from limit switches, pressure switches, etc., to achieve safe control of chemical production processes and prevent dangerous situations like leaks and overpressure.

• Power Industry: Used for safety monitoring and protection of power grids. It can monitor the switch status of generators, transformers, switchgear, etc. (e.g., the opening/closing position of circuit breakers), ensuring the stable operation of the power system, promptly detecting equipment failures, and taking measures to avoid the expansion of accidents such as power outages.

• 
  

• Nuclear Energy Industry: Suitable for safety control of nuclear facilities, meeting the strict requirements for high safety and reliability in the nuclear energy field. It accurately collects digital signals of related equipment to ensure the safe operation of nuclear facilities under various working conditions.

• Manufacturing Industry: In automated production lines, it is used to collect equipment operation status signals (e.g., motor start/stop status, conveyor operation status) and transmit these signals to the control system, achieving precise control and automated management of the production line to improve production efficiency and product quality.

• Water Treatment Industry: Used for controlling and protecting equipment such as sewage treatment and water supply systems. By receiving signals from level switches, flow switches, etc., it realizes automated monitoring of the water treatment process to ensure water quality compliance and stable water supply.
