Schneider Electric RM22TU21 RM22TU21 Network monitor No. of relay outputs: 2

Zelio controller This network monitoring relay monitors three-phase current networks (200-240 VAC) for phase sequence, phase failure and undervoltage. For indication, two relay changers are available, which can be loaded up to 8 A. For undervoltage, the limit value can be set (-20--2%). 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. Three 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.
