ICS TRIPLEX T8122C Trusted TMR Processor Interface Adapter

Product Description

The T8122C is a processor interface adapter for ICS Triplex Trusted TMR safety system, designed to work with T8110B / T8111 TMR processors. This variant enables Modbus Master function, acting as a communication bridge between the Trusted safety controller and external devices. It supports high integrity data transmission under triple modular redundant architecture, widely used for SIL3 safety instrumented systems. It is powered by the TMR processor backplane and installed inside the Trusted controller chassis.
