Technical Introduction
The TRICONEX 9668-110 (7400172-110 / 3000590-110) is a 16-point non-commoned relay output termination panel for Tricon safety systems. The Tricon technical documentation identifies 9668-110 as a termination panel compatible with the 3636R and 3636T 32-point relay output modules.
This is field termination hardware, not a standalone Tricon I/O processor. Each 9668-110 panel handles 16 output points, with separate LOAD and field-power connections and individual fuse protection. A 32-point compatible relay-output module requires two termination panels for all 32 points.

The Tricon technical product guide cross-references 9668-110 → ETA 3000590-110 → cable 4000094-110. The Tricon field-termination documentation describes the 9668-110 as a 16-point non-commoned relay-output panel with 16 LOAD terminals, 16 PWR terminals, and 16 fuses.
Field Engineer’s Tech Notes
- Confirm the I/O module before ordering the panel. The documented 9668-110 is intended for the 3636R/3636T relay-output modules. Do not substitute it for a termination panel intended for another Tricon I/O architecture.
- Check the fuse and field-power wiring during replacement. The panel has individual fuse protection for its 16 output points. Photograph the existing LOAD/PWR wiring and fuse positions before disconnecting the old panel; a wiring error can leave the Tricon output module healthy while the field load remains inoperative.
Adaptive QA & Testing Protocol
QA begins with verification of 9668-110 / 7400172-110 / 3000590-110, followed by inspection of terminal blocks, fuse holders, connectors, PCB traces, mounting hardware, and signs of overheating or corrosion.
Functional verification should be performed with the applicable 3636R or 3636T relay-output module and Tricon test environment. Each termination point can be checked for continuity and correct field-side routing, while fuse condition and relay-output switching should be verified according to the approved Tricon maintenance procedure.
Inspection photographs, test reports, and available test videos can be provided upon request.
Buyer’s FAQ
Q: Is 3000590-110 the same part as TRICONEX 9668-110?
A: Yes. Tricon technical documentation cross-references 9668-110 with ETA part number 3000590-110, while other parts references also identify 7400172-110 with the same termination board.
Q: Is 9668-110 an I/O module?
A: No. It is a field termination panel. The documented 9668-110 is a 16-point non-commoned relay-output termination panel used with compatible Tricon relay-output modules.
Q: Which Tricon modules are compatible with 9668-110?
A: The Tricon field-termination documentation lists 3636R and 3636T, both 32-point relay-output modules. Two 16-point termination panels are required to terminate all 32 points.
Q: What should I provide when requesting a replacement?
A: Provide the complete marking 9668-110 / 7400172-110 / 3000590-110, the connected Tricon I/O module number, interface-cable number if visible, and photographs of the existing termination panel.
