Description
Zelio controller This network monitoring relay monitors three-phase systems (220-480 VAC in 6 steps) for phase sequence, phase failure, phase asymmetry (5-15%), over and undervoltage in window mode (-20- 2%/+2-+20% depending on the voltage). For the message 2 relay changers are present, which are loadable up to 5 A. The limit value for the asymmetry, under and overvoltage range and a switch-off delay can be set for the output. Settings are made via control elements on the front that can be protected against changes using a transparent cover. Three LEDs indicate the status. The width is 35 mm and it is installed on the DIN rail. The cable is connected via screw terminals.
