Phoenix Contact MINI MCR-SL-R-UI | Potentiometer to Analog 4-20mA Converter
Phoenix Contact MINI MCR-SL-R-UI signal conditioner. Converts 100Ω-100kΩ potentiometer input to 4-20mA or 0-10V. 24V DC power, 6.2mm slim DIN rail module.
Product Overview
The Phoenix Contact MINI MCR-SL-R-UI (Order No. 2864095) is an ultra-slim resistance and potentiometer transmitter for industrial signal conditioning. It converts a variable resistance input (100 Ω to 100 kΩ) into a standardized analog output signal (4-20 mA, 0-10 V, etc.). With a width of just 6.2 mm, it provides electrical isolation between the sensor input and the control system output, protecting against interference and ground loops. Configuration is simplified via DIP switches on the side of the module.
