Detailed Description
The current sensor S1 records the current in a cable with a hall sensor. At currents of app. 5-30 A) the
transistor-outputs switch and report a current in the monitored cable. Simultaneously the yellow LED is on.
The current sensor can be fixed with a cable fastener with cable in parallel to the housing (apply to 1 phase
only). Thus, it can be mounted subsequently without disconnecting the cable.
As supply-voltage DC 24 V / 12 ... 32 mA are required.
