Schneider Electric RM22UA33MR RM22UA33MR Monitoring relay No. of relay outputs: 2

Zelio controller This voltage monitoring relay monitors a measuring circuit for exceeding or falling short of the set limit value (15-500 VAC/DC). You can choose between exceeding, falling below or falling short in window mode. An optional error memory can be selected, which holds the error message until a reset is performed. For indication, two relay changers are present that can be loaded with up to 8 A. The functioning, the limit value, the switching hysteresis and a drop off delay are adjustable. Settings are made via control elements on the front that can be protected against changes using a transparent cover. With the illuminated scale arrow the setting of the potentiometers can be clearly recognized even from a distance. The diagnostic switch on the front allows the output relays to be switched off to test the overall application. When the clear cover is closed, the diagnostic switch is automatically reset. The wide-voltage power supply (24-240 VAC/DC) enables a universal application. Two LEDs indicate the status. The width is 22.5 mm and it is installed on the DIN rail. The cable is connected via screw terminals.
