Foxboro CP30B is a Control Processor 30, Style B for Foxboro I/A Series. I/A Series regulatory and sequential control with Style B processing hardware.
I/A Series control with connected FBMs and fieldbus cluster I/O. Unlike the CP30, CP30B uses an AMD 486DX5 at 133 MHz and ECC memory protection in its official specification.
The single-width CP30B can be installed singly or as two CP30B modules in a fault-tolerant configuration.

Confirm current manufacturer support and installed-system requirements before replacing CP30B.
CP30B performs regulatory, logic, timing and sequential control, plus data acquisition and alarm handling in an I/A Series installation.
The manufacturer lists Fieldbus Modules, Fieldbus Cluster I/O cards, and SPECTRUM, SPEC 200 and SPEC 200 MICRO Migration Integrator I/O. The actual supported arrangement depends on the installed fieldbus and system configuration.
A non-fault-tolerant station uses one single-width CP30B module. A fault-tolerant station uses two CP30B modules operating in parallel with separate Nodebus and Fieldbus connections.
The official specification gives up to 24 local FBMs, or up to 64 FBMs on an extended fieldbus with no more than 24 per isolator. Check the installed isolators and fieldbus topology before expansion.
Yes, the manufacturer documents SPECTRUM Migration Integrator interfaces through Fieldbus Processors with built-in isolators. The control strategy and integrator type must be matched to the existing UCM, FIO, UFM or UIO subsystem.
Verify the assigned station definition, Nodebus and Fieldbus connections, the connected I/O configuration and alarm/data-acquisition operation. The official specification describes power-up, run-time/watchdog and off-line diagnostics.
Provide the exact CP30B designation and revision, whether the station is single or fault-tolerant, its Nodebus/Fieldbus and migration-I/O arrangement, and the installed software and license context.
Send the complete model, quantity, destination and nameplate photo. We will verify identification details before confirming availability and lead time.
Technical data is based on manufacturer-owned documentation for CP30B. Final suitability must be checked against the exact installed unit and current official documentation.
