Triconex 3625 Supervised Digital Output Module

The Triconex 3625 is a 32-channel commoned digital output module built on TMR triple modular redundant architecture for Tricon safety instrumented systems. It executes safety shutdown logic and field equipment control commands transmitted from the main processor module.

This module supports supervised and non-supervised operation modes with comprehensive circuit diagnostics. It complies with SIL3 safety requirements and enables hot-swap maintenance. Widely adopted in oil & gas, power and petrochemical industries for SIS cabinet maintenance, system expansion and spare parts stocking.
