Triconex 3601T Triconex 3601T-1 Triconex 3601T-2 Triconex 3601T 4

The Triconex 3601T Digital Output Module is a robust safety I/O component engineered for deployment in Triconex Safety Instrumented Systems (SIS) where high‑integrity actuation of field devices is critical. Designed with fault‑tolerant principles, it delivers 16 discrete output points optimized for driving higher voltage DC loads (typically 120 – 150 VDC range) used in industrial solenoids, contactors, safety trip coils, and other heavy‑duty actuation devices.

Built to integrate smoothly within a Triple Modular Redundancy (TMR) architecture, the 3601T ensures that safety decisions are executed reliably and that failure modes are detected early—supporting continuous diagnostics and system availability in demanding process applications.

Product Applications

The 3601T module is ideal for safety‑critical applications that require high‑voltage discrete outputs, including:

Emergency Shutdown (ESD) Systems – Drives high‑voltage solenoid valve coils and trip actuators
Fire & Gas (F&G) Safety Logic – Activates protective or isolation devices at higher DC voltages
High Integrity Pressure Protection Systems (HIPPS) – Issues verified safety outputs to safety trip circuits
Process Interlock Systems – Interfaces with industrial controls requiring DC loads > 100 V
Turbomachinery & Rotating Equipment Safeguards – Sends discrete commands to protective relay coils

This module’s ability to handle elevated DC voltages makes it well‑suited for industrial installations where 24 V outputs are insufficient and robust actuation at higher levels is needed.
