Product Introduction
The TRICONEX 9860-610 is an eight-point analog output termination panel used with Tricon safety controllers. Its primary purpose is to provide the field wiring interface for 3805E and 3805H 4–20 mA TMR analog output modules. It is also listed as a compatible termination option for the 2870H HART analog output interface.
This distinction matters during procurement. The 9860-610 is not the active analog output electronics and should not be treated as a replacement for a 3805E or 3805H module. It is the field termination hardware between the Tricon I/O system and the plant-side wiring.
Application Scenarios & Field Pitfalls — The Engineer’s Perspective
Engineering Pain Point
A termination-panel replacement can look simple until the installed Tricon configuration is opened. The panel, I/O module, cable assembly, field wiring, and termination style all have to match. A visually similar Tricon termination panel can have a completely different signal function.
9860-610
Typical Applications
- Tricon 3805E analog output systems — field termination for eight 4–20 mA output points.
- Tricon 3805H configurations — provides the field interface for the H-version analog output module.
- 2870H HART analog output interface — listed by Tricon documentation as a compatible termination option.
- Legacy Tricon maintenance — replacement for damaged terminal panels, connectors, or field-wiring interfaces.
The v9–v10 termination guide also lists the 9860-610 in the RG 1.180 termination-panel category, while the 9860-610F is the specifically documented RG 1.180 version.
Technical Pitfalls
1. Do not order it as an analog input panel.
Some commercial listings incorrectly describe 9860-610 as an analog input termination panel. Tricon documentation identifies it as a current-output termination panel for 3805E/H and 2870H.
2. Do not confuse the panel with the I/O module.
The 3805E/3805H provides the analog output electronics. The 9860-610 provides the field termination interface.
3. Verify the exact panel suffix.
The standard 9860-610 and 9860-610F should not automatically be treated as interchangeable. The F version is specifically documented for applications requiring RG 1.180 compliance.
4. Check the cable assembly.
The Tricon cross-reference identifies 3000770-610 as the ETA/base assembly associated with 9860-610 and lists 4000157-510 as a corresponding cable part number in the v9–v10 documentation.
5. Verify the installed I/O revision.
A termination panel replacement does not establish compatibility with every Tricon analog output module. Confirm whether the installed system uses 3805E, 3805H, or 2870H before purchasing.

Procurement Note
For a replacement 9860-610, match the panel part number, module type, termination category, cable assembly, and system generation before shipment. If the existing panel is being replaced during a live plant outage, photograph or record every terminal and cable designation first. A termination-panel mismatch can create field-loop errors even when the Tricon I/O module itself is functioning normally.
