RM22UA32MR Over-/undervoltage monitoring with memory

Harmony Control. This voltage monitoring relay monitors a measuring circuit for exceeding or falling below the set limit value (1 - 100 V AC/DC). You can choose between over, under and over/under in window mode. Optionally, an fault memory can be selected that stores the fault message until a reset. Two relay changeovers with a load capacity of up to 8 A are provided for signalling. The operating mode, limit value, switching hysteresis and a dropout delay can be set. The settings are made via the control elements on the front, which can be protected against modifications under a transparent cover. With an illuminated scale arrow, adjustment of the potentiometers can be seen very clearly even from a distance. The diagnostic switch on the front enables the output relays to be interrupted for testing the overall application. The diagnostic switch is automatically reset when the transparent cover is closed. The wide-voltage power supply (24 - 240 V AC/DC) enables universal use. Two LEDs indicate the status. The overall width is 22.5 mm, and mounting is on the DIN rail. The cable is connected via screw terminals.
