Schneider Electric RM22UA21MR RM22UA21MR Monitoring relay No. of relay outputs: 2

Zelio controller This voltage monitoring relay monitors a measuring circuit for exceeding the set limit value (0,05-5 VAC/DC). For indication, two relay changers are present that can be loaded with up to 8 A. The limit value and the switching hysteresis 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.
