TRICONEX DI3301 Digital Input Module

TRICONEX DI3301 Digital Input Module

Product Details Introduction

Triconex DI3301 is a highly reliable digital input module designed for use in Triconex triple redundant safety systems. It is mainly responsible for collecting on-site switch signals and providing safety data acquisition function under a triple fault-tolerant architecture, widely used in industrial environments with extremely high safety requirements.

Core functions

Receive digital signals from on-site devices (such as dry contacts, limit switches, relay outputs, etc.)

Input the signal into the redundant processing system of the Tricon controller

Provide signal filtering, isolation, anti shake and other functions to improve signal quality

Support synchronous operation with other I/O modules to achieve safety control logic
