ICS TRIPLEX T8403C Trusted Digital Input Module in stock

ICS TRIPLEX T8403C is a triple modular redundant digital input module for ICS Triplex Trusted TMR SIS safety instrumented system. It collects 24VDC discrete digital signals from field safety switches, valve position feedback and emergency trip sensors for safety interlock and ESD protection logic processing.

This module adopts SIL3 safety certification, supports hot-swap operation and per-channel circuit diagnosis, with conformal coating for dusty and humid industrial sites. It is rack plug-in mounted, widely used for safety cabinet maintenance, spare parts replacement and plant safety instrument system retrofit projects.
