ICS TRIPLEX T9481 Trusted 8 Channel Isolated Analog Output Module

ICS TRIPLEX T9481 is an 8-channel isolated analog output module for the Trusted safety instrumented system. It receives digital control commands from the safety processor and converts signals into 4-20mA analog outputs to control field valves, actuators and regulating devices, with built-in continuous channel diagnostic functions.

This module supports simplex, dual and TMR triple modular redundant configurations to meet IEC61508 SIL3 safety requirements. It supports hot swap on Trusted backplane without interrupting safety system operation, widely supplied as spare parts for maintenance and replacement of ESD and process safety control systems.
