2>. The input signal is compatible with NPN and PNP, and is compatible with PLC equipment such as Mitsubishi, Panasonic, Siemens, and domestic PLC.
3>. The signal input voltage is 3.3V.
4>. Protection measures: Each channel of the input adopts photoelectric isolation module to effectively protect the safety of the control terminal; at the same time, it is equipped with eight bipolar status indicators. The output has diode anti-surge protection, and the power supply has diode anti-reverse protection.
5>. Wiring: VCC and GND are the power supply ports of this module, and are wired according to the prompt voltage. COM is connected to the signal control terminal common pole, 1-4 is connected to each channel control signal; the output of the controlled device is open drain output, labeled O1-O4.
6>. Installation: DIN35mm rail installation, convenient and fast!
