More Information

Overview Manuals Compact Mounting Loop Integration Service Replacement Application
  • Use only on the documented Compact 200 baseplate
  • Preserve HART device and loop-power configuration
  • Do not substitute standard-module dimensions or mounting data

RH101AB is selected for compact-density Foxboro installations that need the FBM214B HART function in a different mechanical format.

The 16-slot horizontal baseplate, narrower module width and compact connector arrangement distinguish it from RH927AH standard hardware.

Before exchange, verify enclosure depth, baseplate slot, RH924JH wiring and any RH903SV balun used with a shared external supply.

Availability, condition, price, and shipping time for RH101AB are confirmed during quotation.

  • Use the documented 16-slot horizontal baseplate
  • Allow for 15.0 cm depth including connectors
  • Keep access for the compact baseplate release and cable
  • Preserve the eight isolated loop definitions
  • Match each HART tag to the restored channel
  • Install RH903SV when the shared-supply design requires it
  • Do not substitute standard FBM214B mechanics
  • Inspect compact connectors before seating the module
  • Validate both analog and digital device communication
  • High-density Compact 200 HART input cabinets
  • Compact FBM214B module replacement
  • Eight smart-transmitter loops with limited panel width
Description
o RHFoxboro RH101AB combines eight isolated current-input channels with per-channel HART messaging in the Compact 200 form factor.

It communicates with supported field devices through dedicated FSK modems while returning each analog process value to the control database.

Its compact mechanical design increases cabinet density but requires the correct horizontal baseplate and connector clearances.

Technical notes
RH101AB is the compact Foxboro DCS version of the FBM214B HART analog input module and has different physical and environmental limits from RH927AH. Before replacement, verify compact-platform compatibility, termination assembly, loop power and controller configuration.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Can Foxboro RH101AB be installed in a standard 200 Series FBM baseplate?
No assumption of cross-mounting is valid; RH101AB is documented for the Compact 200 16-slot horizontal baseplate.
Can Foxboro RH101AB directly replace RH927AH?
They share the FBM214B function but use different mechanics and baseplates, so they are not treated as a physical drop-in swap.
Which field termination is used with Foxboro RH101AB?
The official compact specification identifies RH924JH with a Type 1 cable; confirm the quoted stock includes neither unless explicitly stated.
When does Foxboro RH101AB require RH903SV?
Use the documented RH903SV cable balun when a common external supply powers two or more HART loops and crosstalk prevention is required.
Why can Foxboro RH101AB fit the slot but fail to initialize?
Check Compact 200 baseplate compatibility, connector seating, controller software support, slot declaration and restored module configuration.
What should be archived before changing Foxboro RH101AB?
Save the compact-baseplate position, module and TA labels, device tags, loop supplies, channel settings, alarms and communication diagnostics.
How should Foxboro RH101AB be commissioned?
Verify the compact hardware path, test all eight analog loops and HART devices, review diagnostics and confirm a controlled process response.
