Foxboro CM400YH FBM07 Contact/DC Input Module

The Foxboro CM400YH FBM07 is a 16-channel digital input module designed for integration within the Foxboro I/A Series Distributed Control System (DCS). It provides real-time monitoring of discrete field states by accepting both dry contact closures and DC voltage signals across isolated input channels.

Signal Configuration and Channel Isolation

The module contains 16 channel-isolated inputs, which prevent electrical noise and ground loops from affecting measurement accuracy across channels. Each channel interfaces directly with discrete field devices such as limit switches, relay contacts, proximity sensors, and auxiliary status circuits.

Individual LED indicators on the front panel provide visual status updates for each discrete input channel along with overall module operational health. The module utilizes a dual-compartment housing design that physically separates field terminal wiring from the internal processing electronics, allowing safer maintenance and easier module replacement.

System Connectivity

The CM400YH FBM07 connects to the I/A Series system via standard Fieldbus communications through its base module structure. It supports expansion configurations to increase I/O point density within standard control enclosure layouts.
