Module Description:
1. using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;
2. fault-tolerant design, even if the control line is broken, the relay will not operate;
3. the power indicator (green), the relay status indicator (red)
4. the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient
Module Interface:
1. DC+: positive power supply (VCC)
2. DC-: negative power supply (GND)
3. IN: can be high or low level control relay
Relay Outputs:
1. NO: normally open relay interface
2. COM: Common Interface Relays
3. NC: normally closed relay interface
High and low level trigger options:
It is low level trigger when jumper connect to LOW pin
It is high level trigger when jumper connect to HIGH pin
Package Include:
