Wago 750-496 8-channel analog input module 0/4-20 mA Single-ended configurable

Why Choose the WAGO 750-496 Analogue Input Module?

The WAGO 750-496 is a high-density 8-channel analogue input module designed for the WAGO I/O System 750. It enables PLCs and industrial controllers to measure 0–20 mA and 4–20 mA current loop signals from sensors, transmitters and process instrumentation with high accuracy.

Each input channel converts analogue current signals into digital process values that can be processed by the automation controller. The module is ideal for monitoring industrial transmitters measuring pressure, temperature, flow, level and other process variables.

The module also provides a 24 V sensor supply, allowing direct connection of two-wire field transmitters. Its signals are electrically isolated and transmitted with a 12-bit resolution, ensuring reliable and accurate data acquisition in industrial control systems. :contentReference

Industrial Current Loop Monitoring

The 4–20 mA current loop is one of the most widely used signal standards in industrial automation because it provides reliable transmission over long distances and strong immunity to electrical noise. Sensors and transmitters commonly use this format to communicate process measurements to PLCs and control systems.

The WAGO 750-496 module converts these current loop signals into digital values that automation controllers can process. Combined with other modules in the WAGO 750 Series distributed I/O platform, it enables scalable architectures for industrial monitoring and process automation.

Typical Applications

• Industrial process instrumentation monitoring.
• Integration of pressure, flow, level and temperature transmitters.
• Manufacturing and process automation systems.
• Energy and utilities monitoring installations.
• Distributed PLC and remote I/O architectures.
