Why Choose the WAGO 750-491 Analogue Input Module?
The WAGO 750-491 is a high-precision 2-channel analogue input module designed for the WAGO I/O System 750. It enables PLCs and industrial controllers to measure ±10 V analogue voltage signals from sensors, controllers and industrial instrumentation.
Each input channel captures voltage signals with high resolution, allowing automation systems to monitor process variables such as position, speed feedback, control voltages and other analogue measurements. The module converts these signals into digital data that can be processed by the automation controller.
Designed for distributed automation systems, the module integrates directly with WAGO fieldbus couplers and programmable controllers. Its compact DIN-rail housing and CAGE CLAMP® spring terminal technology provide reliable connections and quick installation within industrial control panels.
