Schneider Electric Level relay
Zelio controller This level relay monitors the level of conductive, non-flammable liquids (conductive measuring principle) as limit switches. It can also be used to control fluid levels in a 2-point control during filling and emptying. Conductive level electrodes are also suspended in the tank. The measuring principle makes it possible to distinguish between liquid and foam. For indication a relay changer is available that can be loaded up to 8 A. The resistance value (5 k-100 kOhm) can be set as a limit value. 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 enables a universal use. Two LEDs indicate the status. The width is 22.5 mm and it is installed on the DIN rail. Supply voltage is 380-415 VAC. The cable is connected via screw terminals.This text is machine translated.
