Why Choose the WAGO 750-494 Analogue Input Module?
The WAGO 750-494 is a high-precision 2-channel analogue input module designed for the WAGO I/O System 750. It allows PLCs and industrial controllers to measure 0–20 mA analogue current signals from sensors, transmitters and instrumentation devices used in industrial automation systems.
Each input channel converts incoming current loop signals into digital process values that can be processed by the automation controller. This makes the module suitable for applications involving industrial transmitters such as pressure, temperature, flow and level sensors where accurate current loop measurement is required.
The module integrates directly with WAGO fieldbus couplers and programmable controllers, forming part of a scalable distributed I/O architecture. Its compact DIN-rail design and CAGE CLAMP® spring terminal technology allow fast installation and reliable electrical connections in industrial control cabinets.

Industrial Current Loop Instrumentation
Current loop signalling is widely used in industrial automation because it provides reliable measurement transmission across long distances with strong immunity to electrical noise. Sensors and transmitters commonly output analogue current signals that must be accurately measured by PLCs and control systems.
The WAGO 750-494 module converts these analogue current signals into digital values that can be processed by automation controllers. Combined with other modules in the WAGO 750 Series distributed I/O platform, it allows engineers to build flexible monitoring and control architectures for industrial processes.
Typical Applications
- Industrial process instrumentation monitoring.
- Integration of pressure, flow, temperature and level transmitters.
- Manufacturing and process automation systems.
- Energy and utilities monitoring installations.
- Distributed PLC and remote I/O architectures.
