Core functions and features

Function Positioning:

DI3361 is a digital input module in the TRICONEX safety control system, used to collect the on-off status signals of on-site equipment (such as valve position, sensor alarm, etc.), and is suitable for high-reliability industrial safety systems (such as ESD, F&G).

Core features:

Redundant design: Supports triple module redundancy (TMR), ensuring that a single point of failure does not affect system operation.

Isolation protection: Electrical isolation between channels (≥1500 V DC), with strong anti-electromagnetic interference ability.

Self-diagnostic function: Built-in LED status indicator light, providing real-time feedback on the health status of the module.
