Information
- P0931RQ cable selection depends on the Type 4 termination scheme and the matched discrete-output path.
Engineering boundary: Connector fit alone does not settle cable selection
Acceptance focus: Recheck the complete affected signal path
The catalog specifies 26 AWG conductors and a 2.0 m cable length for this code. The Type 4 designation distinguishes it from other P/PVC termination cables, including the separately specified Type 1 P0931RM. The Type 4H family is a different conductor-size option for longer runs, so the Type 4 designation and 26 AWG construction must remain with this exact code.
Replacement decisions must compare the installed cable type, connector pair and host termination plan. Preserve the existing route and verify each channel that passes through the cable after reconnecting. After replacement, test the affected output path from command through the termination assembly to the field load under the approved safe-work plan.

Foxboro P0931RQ installation guide
Apter Power guide: match the cable type and connector, control external field power and test affected outputs. PDF, 3 pages.
Application scope: Preserve the 26 AWG Type 4 construction and exact mating arrangement; output load ratings belong to the FBM and TA, not the cable alone.
-
Termination interconnect
Join a compatible 200-series FBM to its field termination assembly. The field load and output rating come from the paired FBM242 and TA design. -
I/O cabinet replacement
Restore the exact cable type after jacket or connector damage. Confirm the 26 AWG Type 4 code rather than selecting by the two-metre length alone. -
Signal-path maintenance
Check the cable path while diagnosing a multi-channel field fault. A common fault across outputs can implicate the shared cable or connector path. -
Cabinet rework
Retain approved connector orientation and routing during service. The Type 4H option in the family is separately coded for long-run voltage-drop concerns.
Confirm P0931RQ and Type 4 before fitting. The two-metre length alone does not establish Type 4H equivalence.
Match the FBM and termination assembly connection plan. Use the FBM242 and TA part numbers to confirm the matching output path.
Check pins, shells and strain relief. Small connector damage can affect several externally powered outputs.
Avoid crushing, sharp edges and unsuitable bend radius. Preserve enclosure routing and the specified separation from power conductors.
Isolate affected I/O before disconnection. Field power can remain present even when the FBM is out of service.
Check continuity and host indication after service. Confirm both host command and actual field-load response for affected points.

FAQ View All FAQ
-
Why is P0931RQ not interchangeable with P0931RM on length alone?The two codes identify different termination-cable types; P0931RQ is Type 4, 26 AWG, while P0931RM is Type 1.
-
What does a multi-channel fault after changing P0931RQ suggest?Check connector seating, cable orientation, mating termination hardware and the complete cable path.
-
What records should be kept for P0931RQ replacement?Retain both endpoint markings, cabinet routing, cable type and list of affected channels.
-
Can P0931RQ be extended by joining two cables?A joined extension is not established by the catalog description. Use the approved I/O termination design and specified length.
-
How should P0931RQ be inspected before energizing?Check the 26 AWG cable jacket, termination ends, strain relief and pin alignment.
-
Does P0931RQ determine the FBM channel function?No. Channel function is defined by the paired FBM and control configuration; this item is an interconnect.
-
What is the commissioning test for P0931RQ?Verify each affected point at its field termination and host indication after connection.
-
How should electromagnetic interference be considered for P0931RQ?Preserve the designed cable route and separation from power wiring; follow the installed system grounding plan.
