Foxboro FBM211 Invensys 0 to 20 mA Input Module

Description

The Foxboro FBM211 Invensys 0 to 20 mA Input Module is a high-performance differential input unit belonging to the Foxboro I/A Series, designed for industrial automation applications. Its core function is converting differential current signals from analog devices such as pressure and temperature transmitters into digital signals for PLC processing, enabling real-time equipment status monitoring and control. Key technical specifications include 16 input channels, supporting 4-20 mA DC current loop input with a maximum per-channel input of 33 mA DC and a full input range of 0 to 20 mA DC. It delivers high measurement accuracy of ±0.1% full scale and a fast update rate of 125ms, ensuring reliable and responsive data capture. Powered by 24V DC, it has a power consumption of 24W at this voltage. Built for harsh industrial environments, it operates within a temperature range of -40 degrees Celsius to +70 degrees Celsius and carries a NEMA 4X protection rating. The module measures approximately 150mm x 90mm x 50mm, weighs around 0.25kg, features DIN rail mounting, and supports multiple communication protocols including RS-485, HART, and Modbus for seamless integration with existing control systems.
