Monitoring relay 230 V AC (max) 2 change-overs Metz Connect 110271 1 pc(s)
Undervoltage monitoring in three-phase networks (each phase against neutral) with fixed threshold, fixed hysteresis and integrated test button. It has been specially developed for emergency lighting systems according to DIN VDE 0108. The device can also be used to monitor a single phase. All unassigned inputs must be connected to the connected phase. If there is a reverse voltage caused by the consumer that is greater than the set threshold value, no error message is output. Message: Relay is switched on (contacts 11-14 and 21-24 closed), LED is off. Fault message: Relay has fallen off (contacts 11-14 and 21-24 open), LED is on. Button press: Relay falls back (contacts 11-14 and 21-24 open), LED switches on. Connection with screw terminals.This text is machine translated.
