Features:
- 32 digital output points, commoned and split into two separate field power groups of 16
- 24 VDC nominal operating voltage, ranging between 16–32 VDC
- 1.7 A maximum per point; handles a 7 A surge per 10 ms
Invensys recommends that the termination panels for the3625A module Is wired in parallel and powered froma singleset of redundant field power sources. The 3625A module maybe powered from four independent field power sources, but only if the voltage fromthose sources is within 5% of the highest voltage supplied. If this restriction is not followed, the module will still operate but may experience voter faults and generateanalarm.
Designed for the most critical control programs, Supervised Digital Output (SDO) modules meet the needs of systems whose outputs remain in a single state for extended periods of time (in some applications, for years). An SDO module receives output signals from the Main Processors on each of three channels. Each set of three signals is then voted upon by a fully faulttolerant quadruplicated output switch whose elements are power transistors, so that one voted output signal is passed to the field termination.
The 3625A Triconex Digital 24VDC Output Module may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.
1.System Version Requirements: The 3625A module is designed for Tricon v10.2 and later chassis configurations.
2.Backward Compatibility: It is a complete replacement for older Triconex 3625 modules.
3.Power Supply Recommendations: It is strongly recommended to connect the terminal blocks in parallel to the same set of redundant power supplies. While the module can accept four independent power supplies, the voltage deviation between the power supplies must be kept within 5% to prevent voter failures or alarms.
1.Emergency Shutdown (ESD): Immediately trips isolation valves, stops pumps, or disconnects fuel supply lines in the event of a critical incident at the plant.
2.Fire and Gas (F&G) System: Activates deluge valves, alarms, flashing lights, and fire suppression systems upon detection of gas or flame.
3.Burner Management System (BMS): Controls the main combustion gas valves and ignition gas valves on industrial boilers, furnaces, and heaters to prevent the accumulation of explosive gases.
4.Turbine Control (TMC): Activates fast-trip solenoid valves on steam turbines or gas turbines to prevent overspeed disasters.
