Foxboro | FBM211 RH914TN | Input Module

Description

The Foxboro FBM211 RH914TN is a high-performance differential input module belonging to the Foxboro I/A series, designed for industrial automation systems. Its core function is converting differential current signals from field devices such as pressure and temperature transmitters into digital signals for PLC processing, enabling real-time equipment condition monitoring and closed-loop control in industrial environments.

Key technical specifications include 16 independent channels, supporting 4-20mA DC current loop input with a broader measurable range of 0 to 20mA DC (each channel can handle a maximum of 33mA DC). It delivers high measurement accuracy of ±0.1% of full scale, with a fast update rate of 125ms to ensure timely data transmission. The module operates on 24V DC power, with a maximum power consumption of 24W at this voltage, and performs reliably across a wide temperature range of -40 degrees Celsius to 70 degrees Celsius, with a NEMA 4X protection rating for durability in harsh industrial settings.

Physically, it measures approximately 150mm x 90mm x 50mm and weighs 0.25kg, featuring DIN rail mounting for easy installation. It supports multiple communication protocols including RS-485, HART, and Modbus, ensuring seamless integration with various industrial control systems. Ideal for applications in oil and gas, petrochemical, power, and manufacturing sectors, it provides flexible, high-precision analog signal acquisition for critical process control.
