1 2 4 8 8V12V24V relay module with light coupling isolation support high and low level trigger development board

One module description:
1. Maximum load of frequent opening interface: AC 250V/10A, DC 30V/10A;
2. Using patch optocouplery isolation, strong driving capacity, stable performance; 5mA touch current;
3. The working voltage of the module is 5V12V24V

4. The module can be triggered by high levels or low levels through the jump line;
5. Fault tolerance design, even if the control line is broken, the relay will not move;
6. Power indicator light (green), relay status indicator (red)
7. The interface design is humane, and all interfaces can be led directly through the wiring terminal, which is very convenient.
8. There are 4 fixed bolt holes, and holes 3.1mm

Two module interface:
1. DC+: The positive pole of the power supply (voltage according to the requirements of relay)
2. DC-: The negative pole of the power supply
3. IN: Can control relay suction and combination at high or low levels
Relay output end:
1. NO: relay often opens the interface, relay sucks the front suspension, and shortly with COM after suction
2. COM: Public interface of relays
3. NC: The relays are constantly closed interface, the relay is short -connected before the combination

High and low level trigger selection end:

1. The jump line is triggered at a low level when it is short -connected;

2. Triggered at a high level when jumping and HIGH are short -connected
