WAGO 750-493 analogue input module with two 4–20 mA current inputs for the WAGO 750 distributed I/O system.
£269.36
The WAGO 750-493 is a precise 2-channel analogue input module designed for the WAGO I/O System 750. It enables PLCs and industrial controllers to measure 4–20 mA current loop signals from sensors, transmitters and industrial instrumentation with high accuracy.
Each channel converts incoming current signals into digital process data that can be used for monitoring and control tasks within automation systems. This makes the module suitable for applications such as pressure, temperature, flow and level transmitter integration in industrial process environments.
The module integrates seamlessly with WAGO fieldbus couplers and programmable controllers, forming part of a modular distributed automation system. Its compact DIN-rail design and CAGE CLAMP® spring terminal technology ensure fast installation and reliable electrical connections within industrial control cabinets.
The 4–20 mA current loop is one of the most widely used signal standards in industrial automation. It offers excellent noise immunity and reliable signal transmission across long cable distances, making it ideal for process measurement applications.
The WAGO 750-493 module converts current loop signals into digital values that PLCs and automation controllers can process. When combined with other modules in the WAGO 750 Series distributed I/O platform, it allows engineers to build flexible automation architectures for process monitoring and machine control.
