DPA53 Series phase monitoring relay with relay output detects under-voltage and improper phase sequence or phase loss. In a DIN-rail-mount housing of just 17.5 mm (0.68 in.), the device can monitor all specified conditions and provide a relay type output that can be set as NC or NO. Voltage monitoring ranges are available for 150-230 V ac and 320-480 V ac. A red LED visually indicates an alarm condition. A time delay built in for relay activation is available as an option.
