Product Introduction

The Foxboro RH926GK is a DIN rail-mounted Compression Termination Assembly (TA) designed for Foxboro Evo™ and I/A Series distributed control systems. It provides a structured interface between field wiring and compatible 200 Series Fieldbus Modules (FBMs), simplifying installation, maintenance, and signal organization within industrial control cabinets.

The termination assembly uses compression screw terminals and a removable termination cable, allowing the TA to be mounted separately from the FBM baseplate. Before installation, always verify the associated FBM model, termination cable type, and certification requirements, as these vary between I/O module families.

  3. Remove cabinet power.
  4. Wait at least 5 minutes before servicing.

Required Tools

  • ESD wrist strap
  • Phillips screwdriver
  • Digital multimeter
  • Wire markers
  • Smartphone for wiring documentation

Preparation

  • Verify the replacement part number is RH926GK.
  • Record the installed FBM model.
  • Photograph all field wiring.
  • Confirm the required termination cable type.

 

Stage 2 – Removing the Existing Assembly (10 Minutes)

  1. Disconnect system power.
  2. Label each field conductor.
  3. Disconnect the termination cable.
  4. Remove the field wiring.
  5. Release the DIN rail latch.
  6. Inspect the DIN rail and connectors for damage or contamination.

⚠️ Retain the original assembly until the replacement has completed commissioning successfully.

 

Stage 3 – Installing the RH926GK (10 Minutes)

  1. Wear an ESD wrist strap.
  2. Mount the termination assembly securely on the DIN rail.
  3. Connect the appropriate Foxboro termination cable.
  4. Reconnect field wiring according to the original documentation.
  5. Tighten all terminal screws to the recommended torque.
  6. Verify cable routing and protective grounding.

Installation Checklist

  • ☑ Correct model installed
  • ☑ DIN rail latch engaged
  • ☑ Wiring verified
  • ☑ Termination cable secured
  • ☑ Ground connection confirmed

 

Stage 4 – Power-Up & Commissioning (10 Minutes)

  1. Check field wiring for shorts.
  2. Restore cabinet power.
  3. Verify the associated FBM initializes normally.
  4. Confirm all I/O channels communicate correctly.
  5. Perform loop checks for every connected signal.
  6. Review controller diagnostics before returning the process to service.

⚠️ If communication or I/O faults occur after replacement, verify the termination cable type, connector seating, and compatibility between the TA and the installed FBM before replacing additional hardware.

 

Frequently Asked Questions (FAQ)

Q1. What is the RH926GK used for?

The RH926GK is a Termination Assembly (TA) that provides the interface between field wiring and compatible Foxboro 200 Series Fieldbus Modules within Foxboro Evo™ and I/A Series control systems.

Q2. Is the compatible with every Foxboro FBM?

No. Each Foxboro FBM family requires a specific termination assembly and termination cable. Always verify compatibility using the FBM Product Specification Sheet before ordering.

Q3. Can the be replaced while the system is energized?

No. Foxboro recommends isolating system power before replacing termination assemblies to prevent equipment damage and avoid unexpected process interruptions.

Q4. What should I inspect before installation?

Verify:

  • Exact part number ()
