Phoenix Contact 2810625 Current Measuring Transducer – MACX MCR-SL-CAC-5-I-UP

The Phoenix Contact MACX MCR-SL-CAC-5-I-UP is a DIN rail-mounted current measuring transducer designed to convert sinusoidal AC currents of 1 A or 5 A into a standard 0–20 mA or 4–20 mA analog signal. Ideal for energy monitoring, panel instrumentation, and control systems, this compact unit features DIP-switch configuration, 3-way electrical isolation, and integrated LED diagnostics.

Its wide supply range from 19.2 V to 253 V AC/DC makes it suitable for universal deployment in automation environments.
