Product Description
The FBM237 (RH914XS) is a high-reliability analog output module for the Foxboro I/A Series and Foxboro Evo distributed control systems. It provides eight individually isolated channels capable of producing 0-20 mA DC control signals, making it ideal for driving final control elements such as valve positioners, variable speed drives (VFDs), and other actuators requiring precise analog setpoints.
Engineered for maximum signal integrity, each channel features galvanic isolation to prevent ground loops, ensuring that a failure in one field circuit does not affect others. With 13-bit resolution, the module delivers smooth, accurate control of process variables. Its rugged, G3-rated construction allows deployment in harsh industrial environments, including corrosive atmospheres.

Frequently Asked Questions
Q: How does the RH914XS differ from the P0914XS?
A: The RH914XS is the RoHS-compliant version of the P0914XS. They are functionally identical with the same performance specifications, but the RH version is manufactured without restricted hazardous substances, making it suitable for modern facility replacements and environmental compliance.
Q: Is this module hot-swappable?
A: Yes. The FBM237 can be removed or replaced while the system is powered. If part of a redundant pair on a redundant baseplate, the standby module maintains output signals during replacement, ensuring zero process interruption.
