Carlo Gavazzi PUA01CD48500V is a 1-phase AC/DC overvoltage or AC overcurrent monitoring relay in a 36 mm plug-in housing. It operates from 24-48 V AC/DC and provides a single SPDT relay output with no time-delay adjustment. The device monitors external voltage in the 2-500 VAC/DC range, and for MI or MP current-sense inputs it accepts 0.4-4 Vp AC, enabling protection against voltage or current excursions in single-phase circuits.
