Description
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 convenientModule Interface:1. DC+: positive power supply (VCC)2. DC-: negative power supply (GND)3. IN: can be high or low level control relayRelay Outputs:1. NO: normally open relay interface2. COM: Common Interface Relays3. NC: normally closed relay interfaceHigh and low level trigger options:It is low level trigger when jumper connect to LOW pinIt is high level trigger when jumper connect to HIGH pinPackage Include:6x relay module
