TMR Digital Output Module

The Triconex 3604E is a 16-channel Triple Modular Redundant (TMR) Digital Output Module for the Tricon Safety Instrumented System (SIS). It is a 24 VDC, non-commoned, optically isolated output module designed to drive safety-critical field devices such as solenoid valves, relays, and actuators in Emergency Shutdown (ESD), Fire & Gas (F&G), and Burner Management Systems (BMS).

The ICS Triplex T8461C is a 40-channel Triple Modular Redundant (TMR) Digital Output Module designed for the Trusted TMR Safety Instrumented System (SIS) platform. It delivers software-selectable 24V/48V DC sourcing output with 0.75A per channel, using triple-redundant hardware voting (2-out-of-3) to eliminate single points of failure.
