Phoenix Contact: Wide-range DC voltage transducers

April 4, 2017
Phoenix Contact’s newest DC voltage transducer has a user-friendly programming interface and optional push-in connection technology (PT); the MACX MCR-VDC transducer family recently secured UL/cUL listing, making it suitable for use in a wide range of applications.

The new transducers have the same footprint and technical capabilities as the obsolete MCR-VDC-UI-B-DC transducer, but the new design features selectable analog outputs ranging from 2 to 10 V/4-20 mA (unipolar) or ±10 V/0 to ±20 mA (bipolar). An optional teach-in function simplifies zero/span adjustments. The new series can operate between -25 and 60 deg. C, compared with a range of -25 to 50 deg. C on the obsolete module.

By monitoring voltage with the MACX MCR-VDC, it is easier to spot maintenance issues and to ensure the continuous and reliable operation of any DC system between 0 and ±660 V DC. Application examples include DC power supplies, battery banks, solar arrays and combiner boxes, DC power buses, and DC generators.
