Foxboro FBM215/218 RH926SP HART Output Interface Module

Configured for high-accuracy signal execution in Foxboro I/A Series system architectures, the Foxboro FBM215/218 RH926SP (FBM215/218 HART Communication Output Interface Module) provides direct physical/electrical execution. This 8-channel hardware interface translates host control algorithms into 4-20 mA current signals while simultaneously managing bi-directional HART digital communication with intelligent field positioners and output transducers.

DCS Process Isolation and HART Protocol Transmission

The Foxboro FBM215/218 RH926SP utilizes channel-to-channel isolation across all eight output paths to prevent earth loop interferences from impairing valve positioning commands. Each loop transmits continuous 4-20 mA analog control levels while superimposing digital HART Frequency Shift Keying (FSK) signals for real-time diagnostic reporting from smart field devices. Conformal-coated circuit board subassemblies protect active components against atmospheric corrosives in ISA S71.04 Class G3 harsh industrial environments, stabilizing loop impedance across variable plant operating cycles.

Frequently Asked Questions

Q: Does removing an individual output signal line disrupt HART communication on adjacent channels of the FBM215/218 RH926SP?

A: No, each of the eight output channels features complete channel-to-channel isolation. Circuit interruption or fault conditions on one channel do not affect analog output accuracy or HART digital signal transmission on remaining channels.

Q: What mounting hardware is required to install the FBM215/218 RH926SP within an industrial control panel?

A: The module housing clips directly onto standard 32 mm or 35 mm DIN rails inside an IP54-rated protective enclosure without requiring special adapter brackets.

Field Installation Guidelines

Mechanical Mounting: Align the module base keyway with the 32 mm or 35 mm DIN rail inside the enclosure. Press firmly until the retaining latch snaps cleanly into position.
Signal Cable Termination: Route output loop wiring through dedicated wire ducts. Connect field wiring to the corresponding screw or spring-clamp terminals, torqueing threaded clamps to 0.5 Nm (4.4 in-lb).
Shield Connection: Terminate overall cable shields at the primary cabinet grounding bus bar. Maintain shield continuity up to the field device, but leave the shield ungrounded at the field instrument to eliminate circulating ground loop currents.
