TRICONEX 3501E Digital Input Module

• High reliability: Designed for safety instrumented systems, it features redundant design and fail – safe functions, ensuring high availability of the system and stable operation in harsh industrial environments.
• Multiple input types: Supports various digital input types such as switching values and discrete quantities, and can receive input signals in different forms like normally open, normally closed, and passive, meeting the monitoring needs of various on – site equipment.
• High – density integration: A single module can provide 32 digital input channels, improving system integration, reducing the number of modules and installation space, and lowering system costs.
• Wide voltage range: The working voltage is 115VAC/DC, with the AC range being 90 – 155V AC, the DC range being 90 – 155V DC, and the frequency range being DC or 47 – 63Hz.
• Built – in diagnostic function: Each input point is equipped with a built – in diagnostic LED, which is convenient for users to quickly judge the working status of the input point and timely detect and eliminate faults.
• Modular design: Adopts a modular structure, facilitating installation, disassembly and maintenance, enabling quick replacement of faulty modules and shortening system downtime.

• Oil and gas industry: Used to monitor the status of wellhead valves, pipeline pressure switches, liquid level switches and other equipment to ensure the safety and stability of the production process.
• Chemical industry: Can monitor the status of stirrer switches, feed valves, temperature and pressure sensors of reactors, realize safety interlock control, and prevent dangerous accidents.
• Power industry: In power plants and substations, it is used to monitor the status of circuit breakers, disconnectors, relays and other equipment to ensure the reliable operation of the power system.
• Metallurgical industry: Collects and monitors the switching value signals of blast furnaces, converters, continuous casters and other equipment in the metallurgical production process, realizing automatic control and safety protection of the production process.
