TRICONEX 3625 Digital Output Module

TriconeX 3625 (Schneider’s Triconex 3000 series Triple Redundancy (TMR) digital output module, often in the same model system as 3625A), is compatible with Tricon safety control systems and is the core executing component of SIL3 level SIS/ESD/FGS.
Core positioning and architecture
TMR triple redundancy, three channel parallel+voting mechanism, single point of failure does not affect system operation; Compliant with IEC 61508 SIL3 and IEC 61511, certified by T Ü V.
32 channel 24VDC digital output, capable of directly driving industrial loads such as relays, solenoid valves, contactors, etc; Each channel has independent photoelectric isolation (1500VDC), overcurrent/short-circuit protection, complete self diagnosis and LED status indication.
Support hot swapping, online replacement without stopping the machine; High speed communication with processors such as 3008/3009 through the Tricon backplane bus.
Pay attention to differentiation: 3625/3625A are often confused by some suppliers as I/O or input modules; 3625 is DO (digital output), while 3624 is mostly DI (digital input).
Key Technical Parameters Table

Mechanical standard Tricon module size, supports hot swapping
There is no mandatory shutdown order from the original factory, and it belongs to a mature classic model; Brand new original equipment requires quota, with a futures cycle of 8-12 weeks; The inventory of second-hand/refurbished/spare parts is very abundant.
Still widely adopted by SIS systems in operation, with mature maintenance, calibration, and replacement solutions; Recommend prioritizing the Tricon CX platform’s supporting modules for new projects, but upgrading existing systems can be directly compatible and replaced.

Typical Applications and Configuration Suggestions
Industry: Oil and gas, refining and chemical, coal chemical, nuclear/thermal power, offshore platforms, used for ESD emergency shutdown, FGS fire and gas protection, compressor interlocking, valve safety control.
Redundancy and wiring: Each Tricon rack can accommodate multiple 3625 parallel modules; Suggest using the same batch and firmware version; Priority should be given to using independent fuses/circuit breakers for the output circuit; It is strictly prohibited to connect high-power inductive loads in series without surge absorption.
Maintenance points: Regularly read module diagnostic data through TriStation software; Hot plugging must be powered off or operated in the order specified in the manual to avoid electrostatic breakdown; It is strictly prohibited to plug or unplug wiring terminals with power on.
