When high level (PNP) triggers, the signal is connected to the signal positive port, and at the same time,short-circuit the high-level jumper on the circuit board. When the low level (NPN) triggers, the signal is connected to the negative port of the signal,and at the same time,short the low-level jumper on the circuit board.4.The module supportsthe signal full isolation trigger mode. In this mode, when the high level (PNP) triggers, the signal is connected to the positive port of the signal , and the negative port of the signal is connected to the negative terminal of the signal power
