3625 Triconex Tricon TMR Supervised Digital Output Module 24VDC

3625 Triconex Digital Output Module Product Overview

The 3625 module delivers high-reliability control for critical industrial automation programs. This Triple Modular Redundant (TMR) Supervised Digital Output (SDO) module ensures continuous operation for outputs remaining in a single state for extended periods. The 3625 Triconex module receives output signals from main processors across three distinct channels. A fully fault-tolerant quadruplicated output switch votes on these signals using advanced power transistors. This architecture delivers a single voted output signal to the field termination panel.

Integrated voltage and current loopback circuitry pairs with sophisticated online diagnostics. These systems constantly verify the operation of each output switch, field circuit, and load presence. This design provides complete fault coverage without affecting the output signal state. The 3625 Tricon series module supervises the field circuit to detect critical field faults instantly. It identifies loss of power, blown fuses, open loads, missing loads, and field shorts. Failure to detect field voltage or load presence immediately alerts operators via dedicated LED alarm indicators. Contact us at info@oiltechcontrols.com for immediate pricing and stock availability.
