Wago 750-455 4Ai, Se

Why Choose the WAGO 750-455 4-Channel Analog Input Module?

The WAGO 750-455 is a high-precision 4-channel analog input module designed for the WAGO I/O System 750. It allows PLCs and automation controllers to measure standard 4–20 mA current loop signals from industrial sensors and transmitters, enabling accurate monitoring of process variables across distributed control systems.

Each input channel converts analog current signals into digital process data for use by fieldbus couplers or controllers. The module uses a single-ended input configuration with galvanic isolation between the system and field levels, providing reliable signal acquisition and improved protection against electrical interference. :contentReference

Industrial Current Loop Monitoring

Current loop signalling such as 4–20 mA is widely used in industrial automation systems because it enables reliable signal transmission over long cable distances while maintaining strong immunity to electrical noise. These signals are commonly used by field transmitters measuring pressure, flow, level or temperature.

The WAGO 750-455 converts these analog current signals into digital process data that PLCs can analyse for monitoring, alarms and process control. This enables accurate and reliable process supervision across distributed automation architectures. :contentReference
