ICS TRIPLEX T9432 Trusted 8 Channel Isolated Analog Input Module

ICS TRIPLEX T9432 is an 8-channel isolated analog input module for the Trusted safety instrumented system. It collects 4-20mA analog signals from field transmitters and converts them into digital data for the safety processor, with per-channel galvanic isolation and continuous on-board fault diagnostics.

This module supports simplex, dual and TMR triple modular redundant configurations to meet SIL3 safety requirements. It supports hot swap on the Trusted backplane without system shutdown, widely supplied as spare parts for maintenance and replacement of ESD and fire & gas safety control systems.
