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: 6x relay module
