Why Choose the WAGO 750-451/025-000 8-Channel RTD Analog Input Module?
The WAGO 750-451/025-000 is a precision 8-channel RTD analog input module from the WAGO I/O System 750. It enables PLCs and industrial controllers to measure temperature and resistance values from connected platinum and nickel resistance sensors, providing reliable and accurate monitoring for industrial automation systems.
The module directly connects to RTD sensors such as Pt100, Pt200, Pt500, Pt1000, Ni100, Ni120 and Ni1000. Integrated linearisation automatically converts resistance values into temperature data, allowing controllers to monitor thermal conditions across production processes, energy systems and building automation infrastructure. :contentReference
