The Discrete Input Module Foxboro FBM217 P0914TR is a versatile discrete input module engineered for the Foxboro I/A Series DCS. It provides 32 isolated input channels, each accepting a two-wire input from a DC voltage source. Paired with appropriate termination assemblies (TAs), it handles discrete inputs under 60 VAC, 120 VAC/125 VDC, or 240 VAC. This allows the module to perform essential signal conversion, seamlessly interfacing field sensor signals with the system’s Fieldbus.

Designed for flexibility and robust integration, the Foxboro FBM217 P0914TR Discrete Input Module supports discrete voltage monitoring and contact sensing across multiple ranges: 30 VDC, 125 VDC, 120 VAC, and 240 VAC. The TAs incorporate critical features like current limiting devices, high voltage attenuation circuits, optical isolation, and external power connections, ensuring safe and stable operation tailored to the specific I/O requirements.

For enhanced reliability, the FBM217 P0914TR controller DCS I/A series can be installed as a single unit or configured as a redundant pair. In redundant setups, modules are mounted in adjacent odd-even slots on the baseplate and connected through a redundancy adapter. This arrangement doubles the field input current and provides redundancy at the FBM level. The CINR function block in the Foxboro control software manages input reads and initialization for redundant pairs, verifying inputs and ensuring only the highest quality signals drive the control strategy.

When linked to suitable TAs, the FBM217 P0914TR Discrete Input Interface Module effectively replaces older 100 Series FBM subsystems, supporting main and expansion functionality for modules like FBM07, FBM08, FBM20, FBM24, and their expansions. By combining advanced diagnostics, redundancy features, and flexible input handling, the FBM217 Voltage Monitor Foxboro delivers dependable, high-integrity discrete input processing essential for modern industrial automation.
