TheFoxboro FBM2XX (P0931RM)is a 16-channel Digital Input module specifically engineered for the EcoStruxure Foxboro DCS (formerly I/A Series). This module serves as a robust interface for monitoring discrete field devices such as limit switches, pushbuttons, and relay contacts. It is designed to provide high-speed signal processing and electrical protection, ensuring the controller receives accurate real-time data from the plant floor.
Specifications
Part Number:FBM2XX / P0931RM
Input Channels:16 independent points
Input Type:24VDC Contact Sense (Dry contact)
Input Current:2.5mA per channel (nominal)
Isolation:Galvanic isolation between field side and logic side
Operating Voltage:24VDC nominal (sourced from the baseplate)
Input Delay:Configurable filter time (typical 4ms to 50ms)

Features
High-Density Monitoring:Provides 16 discrete inputs in a single module width, optimizing baseplate real estate and reducing hardware costs.
Fault-Tolerant Redundancy:When used with a redundant baseplate and software configuration, two modules can be paired to ensure continuous monitoring during a hardware failure.
Channel Status Indication:Features front-panel LED indicators that provide immediate visual verification of the ON/OFF status for every individual input channel.
Advanced Filtering:Includes software-selectable digital filters to eliminate contact bounce and electrical noise, preventing false signals from triggering process logic.
Hot-Swap Capability:Modules can be removed and replaced without disrupting the operation of other modules on the same baseplate or powering down the system.
