Product Description
Module Overview
The Foxboro FBM217 RH916XZ is a high-density compact discrete input module designed for the Foxboro I/A Series and Evo™ distributed control systems. It is engineered to acquire 32 DC discrete signals from field devices such as switches, proximity sensors, and contact closures, and transmit reliable status data to the control system via a redundant Fieldbus.
This module supports robust signal integrity and high operational reliability in mission-critical environments, including oil & gas, petrochemical, chemical, and power generation facilities.
Signal Processing Capabilities
The FBM217 (RH916XZ) provides 32 group-isolated input channels, ensuring strong immunity to electrical noise and protection against ground loops. Each channel detects on/off states with configurable filtering to mitigate contact bounce. The module supports fast pulse detection up to 250 Hz and configurable debounce times, enabling precise capture of rapidly changing signals.
Communication with the associated FCM or FCP modules is handled through a redundant 2 Mbps Fieldbus interface, ensuring continuous operation even in the event of a module fault.
