TRICONEX 3625C1digital output (DO) module

The TRICONEX 3625C1 is a digital output (DO) module that is part of the TRICONEX safety system. It is mainly used in the field of industrial safety control. The following is its detailed information:

1. Basic Information

Brand: TRICONEX, a brand under Rockwell Automation.
Type: Digital Output (DO) module.
Application Field: Primarily used in industries with extremely high safety requirements such as petroleum, chemical engineering, and electric power. It is designed to output safety-related digital signals and control on-site executive devices (e.g., solenoid valves, contactors).

2. Functional Features

Triple Redundancy Design: Adopts a Triple Modular Redundancy (TMR) architecture, with three independent output channels that process and verify control signals in parallel. It uses a 2-out-of-3 (2oo3) voting mechanism to ensure high reliability and fault tolerance, which can automatically shield single-channel faults and avoid incorrect output actions caused by module failures.
High Safety Level: Certified by TÜV to reach Safety Integrity Level (SIL) 3. It complies with international safety standards such as IEC 61508 and IEC 61511, making it suitable for critical safety loops that require extremely high safety.
Output Capability: Has strong driving capability and can provide output at multiple voltage levels (e.g., the common 24V DC). It can directly drive on-site executive devices like solenoid valves and contactors. Each output point typically adopts a dual-relay design to further enhance output reliability.
Diagnostic Function: Equipped with comprehensive self-diagnostic capabilities to real-time monitor the module’s working status, including power supply, output circuits, and relay status. Once a fault is detected, it can immediately send an alarm signal and feed back fault information to the control system, facilitating timely maintenance and handling.
