Product Details
The Foxboro FCM2F2 RH914YZ, also cataloged as the FCM2F2 Fieldbus Communication Module, operates as a dedicated hardware component for fiber optic media conversion and signal isolation within Foxboro I/A Series DCS platforms. Operating across distances up to 2 kilometers (1.24 miles) between baseplates, this module converts electrical fieldbus signals to optical transmission, providing immunity against EMI, RFI, and lightning transients across an operating temperature range of -40 to +70 deg C (-40 to +158 deg F).

DCS Process Control and Cold Junction Compensation
The Foxboro FCM2F2 RH914YZ module facilitates high-speed fieldbus data transmission while extending FOUNDATION Fieldbus signal coverage over long-distance fiber optic links. Integrated optics isolate fieldbus segments from high-voltage electrical surges, maintaining channel-to-channel isolation between distributed baseplate clusters and central processors. In analog measurement loops routed through linked field modules, this galvanic isolation prevents ground loop interference while auxiliary analog channels process thermal inputs, including 4-20 mA HART loop protocol signals and cold junction compensation (CJC) for temperature sensors.
Frequently Asked Questions
Q: Can the FCM2F2 RH914YZ module be replaced without interrupting active fieldbus communication?
A: Yes, in a dual redundant configuration, the standby FCM2F2 module can be hot-swapped while the primary module maintains active fiber optic communication to the baseplate segment.
Q: What optical connector interface is required for the 2 kilometer fiber optic link?
A: The module accepts standard duplex fiber cables designed for industrial multi-mode optical transmission between baseplate expansion slots.
Field Installation Guidelines
- Align the FCM2F2 RH914YZ module keying guides with the target slot on the Foxboro I/A Series baseplate.
- Press the module firmly into the baseplate backplane connector until the retention latches click to secure physical mounting.
- Clean all optical fiber ends prior to inserting duplex connectors into the module front optical ports.
- Secure fiber patch cables using cable management clips to maintain minimum bend radius rules and avoid optical attenuation.
