3625 Module | Triconex 3625 24VDC TMR SDO Safety Output Card

Product Overview

• The 3625 is a high-performance Supervised Digital Output (SDO) module for the Triconex TMR platform.
• This 3625 module is engineered for critical control programs where outputs remain static for extended durations.
• It utilizes a quadruplicated output switch architecture to ensure a single failure never compromises the safety function.
• The supervised design extends fault coverage to include field-side issues like open loads and blown fuses.

Global PLC Spare HUB's Insight

• The 3625 SDO module provides unprecedented visibility from the logic solver to the final element.
• Loopback circuitry allows the 3625 to verify field circuit health without altering the actual output state.
• The self-protecting design eliminates the need for external fuses at the termination panel.
• This reduces the total cabinet footprint and removes common points of failure in the wiring loop.
• The 3625 is the industry standard for high-reliability solenoids and valve control.

Diagnostic Capabilities & Applications

• Field Supervision: Detects open loads, missing loads, and field shorts in both energized and de-energized states.
• Voted Output Logic: Signals from three Main Processors are voted on by power transistors before field transmission.
• Visual Alarms: Dedicated front-panel LEDs for LOAD alarms per point, plus PASS, FAULT, and ACTIVE status.
• Emergency Shutdown (ESD): Perfect for controlling critical isolation valves and emergency solenoids.
• Fire and Gas (F&G): Driving high-reliability beacons, sirens, and release mechanisms in hazardous zones.

Professional FAQ & Procurement Guide

• Why is the 3625 referred to as a "Supervised" module?
• The 3625 monitors the field wiring integrity, identifying blown fuses or open circuits before a safety action is needed.
• Does this module require external hardware fuses on the termination panel?
• No, the 3625 features an internal self-protecting design that manages electrical faults automatically.
• What happens if the load current drops below the 10 mA threshold?
• The module may trigger a "Load Alarm" indicator because it cannot verify the healthy circuit, though control remains active.
• Can the 3625 be used for non-supervised applications?
• Yes, the 3625 architecture supports both Supervised and Non-Supervised modes via TriStation configuration.
• Selection Advice: What is the benefit of the Dark Blue color code?
• The coding on the 3625 ensures the hardware is only inserted into slots pre-configured for 24V TMR outputs.
