Wago 750-484/000-001 2AI 4-20mA HART Exi Blue

Why Choose the WAGO 750-484/000-001 HART Analogue Input Module?

The WAGO 750-484/000-001 is a specialised 2-channel analogue input module for the WAGO I/O System 750, designed to read standard 4–20 mA current signals from field transmitters while simultaneously supporting HART communication. This allows PLCs and automation controllers to monitor process values and configure smart field devices through the same connection.

Engineered for industrial process automation, the module enables direct integration of HART-enabled transmitters such as pressure, flow, level and temperature instruments. It supplies power to connected two-wire transmitters and captures analogue measurement signals while enabling digital communication with the device for diagnostics and configuration. :contentReference

The module also provides an intrinsically safe interface (Ex i) for field devices located in hazardous environments such as Zone 0 and Zone 1. Installed within the WAGO distributed I/O system, it allows reliable process measurement in chemical plants, energy facilities and other demanding industrial environments. :contentReference

Industrial HART Instrumentation Integration

The HART (Highway Addressable Remote Transducer) protocol allows digital communication with smart transmitters over standard 4–20 mA current loops. This enables engineers to access diagnostic information, device configuration parameters and additional process variables without additional wiring.

The WAGO 750-484/000-001 module combines analogue signal acquisition and HART communication, allowing automation controllers to read measurement data and communicate with field devices through a single distributed I/O platform. Up to four HART dynamic variables per channel can be mapped into the PLC process image for advanced control and monitoring. :contentReference
