1/2/4/6/8 utas relémodul optocsatolóval, 5 V-os bővítőkártyával, magas és alacsony szintű triggerrel Arduino számára
1/2/4/6/8 Way relay module with optocoupler,5V Expansion Board High and low level trigger for Arduino
Module size:
1 way: 50*25*18.5MM
2 way: 50*41*17.5MM
4 way: 75*51*16.5MM
8 way: 142*52*18MM
Module interface:
1. DC : connect to the positive pole of the power supply (voltage according to the requirements of the relay)
2. DC-: Connect to the negative pole of the power supply
3. IN: can control the relay to close
Relay output:
1. NO: The relay is normally open interface, the relay is suspended before it is closed, and it is short-connected to COM after it is closed.
2. COM: relay common interface
3. NC: Normally closed interface of the relay, the relay is short-connected with COM before it is closed, and it is suspended after it is closed
High and low level trigger selection terminal:
1. When the jumper is shorted to LOW, it is low level trigger;
2. When the jumper is shorted with high, it is high level trigger.
