Schneider Electric Triconex 3626X 32-Point SDO Module
The commoned TMR supervised digital output module for 32 safety-related field circuits.
Product Profile
3626X is the Tricon CX supervised digital output module. The official catalog identifies 32 commoned, supervised 24 VDC output points in a TMR architecture.
Correct field termination, common field power, load-supervision settings and the validated safety application remain part of the module boundary.

System Role
Drives 32 documented safety-related discrete output circuits.
Uses TMR processing and output voting.
Supports field-load supervision with approved termination and settings.
Returns module and channel diagnostics to the safety application.
Compatibility
- Match chassis, project release and supported field termination.
- Confirm common field power, fusing and grounding for the output group.
- Document load, inrush, suppression and supervision for every point.
- Preserve project checksum and prove every affected output end to end.
Applications
- Emergency shutdown solenoids and trip relays.
- Fire-and-gas audible, visual or release circuits.
- Burner management and process interlock outputs.
FAQ
What load information is needed for each 3626X channel?
Provide steady current, inrush, suppression, cable, voltage and supervision current.
Why is commoned field power important for 3626X?
Supply isolation and fusing affect the full 32-point group.
Can an older 16-point module replace 3626X?
No automatic substitution is valid; chassis, points, termination and logic differ.
What should be preserved before changing 3626X?
Save the project, checksum, assignments, settings, bypasses and proof-test baseline.
How should replacement 3626X be accepted?
Verify diagnostics and redundancy, then prove every affected final element.
