1PCS 12V 2 Channel Relay Module High and low Level Trigger Dual Optocoupler Isolation 12V Relay Module<\/span><\/strong><\/p>\n

\u00a0<\/p>\n

Module description:
\n1. The module adopts genuine quality relay, the maximum load of the normally open interface: AC 250V\/10A, DC 30V\/10A;
\n2. Using double optocoupler isolation, strong drive capability, stable performance; trigger current 5mA;
\n3. The module operating voltage is 12V;
\n4. Each channel of the module can be triggered by jumper high or low level;
\n5. Fault-tolerant design, even if the control line is broken, the relay will not move;
\n6. Power indicator (green),\u00a02 relay status indicators (red)
\n7. User-friendly interface design, all interfaces can be directly connected through the wiring terminals, very convenient<\/p>\n

Module interface:
\n1. DC+: connect to the positive pole of the power supply (voltage relay 12V)
\n2. DC-: Connect to the negative pole of the power supply
\n3. IN1-IN2: According to the setting of each channel, the corresponding relay can be controlled by high or low level.<\/p>\n

Relay output:
\n1. NO1-NO2: Normal open interface of the relay. Before the relay is closed, it is left unconnected. After picking up, it is shorted to COM.
\n2. COM1-COM2: Relay Common Interface
\n3. NC1-NC2: Normally closed relay interface. Before the relay is closed, it is short-circuited with COM.<\/p>\n

High and low level trigger selection:
\n1. S1-S2 is the high and low level trigger selection for Relay 1 \u2013 2;<\/p>\n

2. When com is shorted to low, the corresponding relay is a low level trigger. When com is shorted to high, it is a high level trigger.<\/p>\n<\/body>","protected":false},"excerpt":{"rendered":"
