1. 3V 1-Channel Relay interface board support photocoupler isolation control,has the output signal indicator,the signal input port can connect SCM IO port, high level signal drive
2. Support dual power supply input ensure high anti-interference ability,high reliability of photoelectric isolation protection
3. With diode continuous flow protection,response time is less than 20 milliseconds,long life of relay can be absorbed 100,000 times continuously
4. The external connection uses the rotary crimping terminal, causes the wiring to be more solid.
5. Equiped with high-current relay, AC250V 10A ; DC30V 10A,each relay has normally open and normally closed contact. Can be selected by jumper relay and TTL or ground.
