FBM204 | FOXBORO | I/O Module 0 to 20 mA

Description

The FBM204 is a high-performance Foxboro I/O module designed for diverse industrial applications, featuring 0 to 20 mA analog input and output capabilities. It is equipped with four 20 mA DC analog input channels and four 20 mA DC analog output channels: each input channel accepts signals from analog sensors such as 4 to 20 mA transmitters or self-powered 20 mA sources, while each output channel drives external loads to produce 0 to 20 mA output signals. All input and output channels are electrically isolated from each other and ground, preventing cross-interference and enhancing operational stability.

Key technical specifications include ±0.1% full-scale accuracy, 16-bit resolution, and an update rate of 250 microseconds per channel, ensuring precise and fast signal processing. The module operates in temperatures ranging from -40 degrees Celsius to 70 degrees Celsius, with a relative humidity tolerance of 5% to 95%, making it suitable for harsh industrial environments. Measuring 78 mm x 14 mm x 104 mm and weighing 0.09 kg, it supports plug, screw, and panel terminal types for flexible installation. Additional features include configurable options for conversion time, fail-safe settings such as hold/fallback, and support for distributed PIDA applications for fast control loops, plus compatibility with standard HART signals. Its rugged design delivers long-term reliable performance for critical industrial control systems.
