Description
Product Description
4-channel Songler relay module 5-24v with optocoupler isolation connector circuit PLC single chip microcomputer
1, using the new original SONGLE relay (SRD-XXVD-SL-C)
2, input signal compatible with NPN and PNP. The control signal voltage is separated from the relay coil supply voltage and can be supplied separately or together.
3, each relay is provided with a group of normally open and normally closed.
4. Each input terminal adopts photoelectric isolation module to effectively protect the safety of the control terminal; It is also equipped with eight bipolar status indicators.
5, Wiring: VCC and GND are the power supply ports of this module, and wiring is according to the marked voltage. COM is connected to the common pole of the signal control end, and 1-4 is connected to each control signal; Controlled electrical output normally closed normally open symbol display, at a glance.
6, the use of large current terminal, can control 220V 10A (maximum) load.
