Foxboro FBM201 | Analog Input Interface Module

Description

The Foxboro FBM201 is an Analog Input Interface Module belonging to the Compact 200 Series I/O subsystem, designed for industrial signal conversion and data acquisition. It features 8 isolated analog input channels, with base models accepting 0 to 20 mA DC two-wire analog sensor input signals; variant models (FBM201b, FBM201c, FBM201d) support additional ranges including 0 to 100 mV DC, 0 to 5 V DC, and 0 to 10 V DC. The module converts field sensor electrical input signals for transmission to FCP controllers, and is electrically compatible with standard HART signals. Key features include channel-to-channel and channel-to-ground electrical isolation, sigma-delta data conversion for high measurement precision, and configurable parameters such as conversion time, integration time, and rate-of-change limits. Its compact, rugged construction is suitable for installation in cabinets within G3 level (harsh) industrial environments, and it is equipped with a terminal assembly (TA) for local or remote field wiring connection. Technical specifications include optional 24V operating voltage, IP67 protection rating, and configurable output frequency options. The module supports loop-powered transmitters, enabling seamless integration with industrial sensing and control systems.
