Foxboro P0914HJB Analog Input Module

Product Description

The P0914HJB from Foxboro is a precision analog input module engineered for the I/A Series Distributed Control System (DCS). It features 8 isolated input channels capable of accurately measuring 4–20 mA and 0–10 V DC signals. Each channel is isolated to minimize interference, while HART protocol support allows remote diagnostics and configuration over standard 4–20 mA loops.

Designed for demanding industrial environments, the P0914HJB supports hot-swappable installation, enabling module replacement without system shutdown. Its compact, rugged design ensures reliability under wide temperature and humidity conditions, making it suitable for oil & gas, chemical, and power generation applications.
