Phoenix Contact RTD Temperature Transmitter Module MCR-RTD/I
This is a German-made industrial temperature transmitter module that operates on 20–30 V DC to convert a 3-wire Pt100 RTD sensor signal (0.0°C to 250.0°C) into an isolated 4–20 mA analog output. It features built-in loop fault detection (3 mA), manual Zero/Span calibration potentiometers, and a local red Power LED.
