AutomationDirect proSense PMRU phase monitoring relays have microprocessor-based design to protect against phase loss, reversal, unbalance, undervoltage and overvoltage conditions. With a variety of user-adjustable settings, PMRU relays also feature a multi-color LED to indicate normal and fault conditions.

The PMRR series provides protection against phase reversal, while the PMRRL series, with an adjustable undervoltage setting knob, protects against phase loss, reversal and undervoltage.
AR series alternating relays feature a three-position selector switch to alternate two loads as normal, or lock the relay to one load or the other. The ARX model is a DPDT cross-wired unit that alternates two loads as normal, or locks the relay to always operate the same load first each time.
Also available are PSFR series pump seal failure relays, which monitor the shaft seals of submersible pumps. Featuring a user-adjustable sensitivity knob, the relays are available in two 8-pin models - SPDT single channel or dual channel relay with two SPNO contacts. Accompanying 8-pin 10 A, 600 V octal sockets are available.
