Schneider Electric RM22UB34 RM22UB34 Monitoring relay No. of relay outputs: 2

Zelio controller This voltage monitoring relay monitors a measuring circuit for exceeding and falling below the set limit value (80-300 VAC/DC). For indication, two relay changers are present that can be loaded with up to 8 A. For exceeding and falling below the threshold a threshold value and the activation or fall delay can be set. 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 supply of the device takes place from the measuring circuit. 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.
