Triconex 3603T 120VDC TMR Digital Output Module

Product Description

The Triconex 3603T is a triple modular redundant (TMR) 16-channel digital output module for the Tricon SIS safety instrumented system. It is a 120 VDC opto-isolated commoned DO module, used to drive field solenoid valves, relays and alarm devices in safety-critical ESD, fire & gas protection systems. It adopts TMR voting architecture with continuous on-board diagnostics, certified for IEC 61508 SIL3 safety applications.
