Overview
The Triconex 3625A is a 32-point TMR Supervised or Non-Supervised Digital Output Module, designed for critical control applications. These modules work with 16-point commoned field termination panels and are suitable for energize-to-trip and de-energize-to-trip applications. You can only install the 3625A module in Tricon v10.2 and later systems.
The 3625A module separates the field power supply into groups of 16 points, maintaining a common return. This modification doesn’t affect its compatibility with all applications that use the 3625 module.
Power Requirements
Invensys recommends wiring the termination panels in parallel and powering them from a single, redundant field power source. Although you can power the module from four independent field power sources, all sources must maintain a voltage within 5% of the highest voltage supplied. Failing to follow this guideline may cause the module to operate with voter faults and trigger alarms.

Notes:
- Field Power Configuration: For the 3625A module, group the field power into sets of 16 points with separate termination panels. Make sure to power all points, including unused ones on non-commoned panels.
- Output Toggle Rate: The maximum output toggle rate is 60 ms. This rate ensures proper I/O diagnostics and helps detect faults effectively.
- Installation: The 3625A module works with low-density systems upgraded to v10.2.x or later. For more details, consult “Appendix I, Low-Density Chassis I/O Module Compatibility” in the Field Terminations Guide for Tricon v9–v11 Systems.
