Product Description
Module Overview
The Foxboro FBM217 RH916CA is a compact discrete input module engineered for the Foxboro I/A Series and Evo™ distributed control systems. It is designed to collect high-density DC discrete signals from field devices and transmit reliable status information to the control processor via the Foxboro Fieldbus.
This module is optimized for applications requiring stable detection of on/off conditions, pulse signals, and contact closures in continuous and batch process environments.
Signal Processing Capabilities
The FBM217 (RH916CA) supports up to 32 group-isolated discrete input channels operating at 24 VDC. Each group isolation enhances noise immunity while maintaining efficient signal density, making the module suitable for crowded control cabinets.
Configurable input filtering allows engineers to suppress contact bounce and electrical noise. Adjustable debounce times and a high pulse counting capability enable accurate monitoring of fast-changing field signals such as proximity switches and encoder outputs.
System Compatibility and Typical Use Cases
Fully compatible with Foxboro Evo™ and legacy I/A Series platforms, this module integrates seamlessly into existing Fieldbus architectures. It is widely deployed in oil and gas installations, chemical processing units, power plants, and other mission-critical facilities where dependable digital input acquisition is required.
