Schneider Electric RM22TR31 RM22TR31 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, undervoltage and overvoltage. For indication, two relay changers are available, which can be loaded up to 8 A. For the undervoltage and overvoltage one limit value is each (-20--2%/+2-+20%) and for the output an activation or drop delay is 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. 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.
