1 2 4 6 8 Channel Relay Module Board DC 5V 12V 24V Shield with Optocoupler High and Low Level Trigger Way Power(24v 4 Channel Red)

relay1 2 4 6 8 Channel Relay Module Board DC 5V 12V 24V Shield with Optocoupler High and Low Level Trigger 1 2 4 6 8 Way Power RelayModule description:1. the module uses genuine quality relay, normally open interfaces Maximum load: AC 250V/10A, DC 30V/10A;2. using SMD optocoupler isolation, driving ability, stable performance; trigger current 5mA;3. the module Operating voltage 5V 12V 24V ;4. the module can be high or low by a jumper setting trigger;5. fault-tolerant design, even if the control line is broken, the relay will not operate;6. the power indicator (green), the relay status indicator (red)7. the interface design of human nature, all interfaces are available through a direct connection terminal leads, very convenient8. module size: 50mm*26mm*18.5mm (L*W*H)Module interface:1. DC+: positive power supply (VCC)2. DC-: negative power supply (GND)3. IN: can be high or low level control relayRelay outputs:NO or NOx: load access terminal, normally openCOM or COMx: load access, commonNC or NCx: load access terminal, normally closedHigh 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 pin
