ICS TRIPLEX T9402 Trusted 16 Channel Isolated Digital Input Module

ICS TRIPLEX T9402 is a 16-channel isolated digital input module belonging to the Trusted safety system series. It collects 24VDC field digital signals and transmits data to the safety processor, with full channel isolation and continuous built-in self-diagnosis for circuit fault detection.

This module supports simplex, dual and triple modular redundant configurations for SIL3 safety applications. It can be hot-swapped on the Trusted backplane without shutting down the safety system, widely used as spare parts replacement for ESD and safety interlock control systems in heavy process industries.
