4.2 Wiring diagram of XKC-Y27B-Dx-NPN
NPN output drives small relays (coil current
≤
100mA) working principle:
When the liquid is sensed, the transistor is turned on and closed, and the relay is energized and closed;
When no liquid is sensed, the transistor is cut off and disconnected, and the relay does not pull in when it is cut off.
