1 relay module with light coupling isolation supports high and low level trigger one road relay extension 5V

One module description:

1. The module uses genuine high -quality relay, and the maximum load of frequent interfaces: 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 5V
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. Module size: 50mm* 26mm* 18.5mm (length* width* height)
9. There are 4 fixed bolt holes, a hole of 3.1mm, and a distance of 44.5mm*20.5mm

Two module interface:

1. DC+: The positive pole of the power supply (voltage according to the requirements of relay, 5V.9V.12V and 24V selection) 2. DC-: connection power supply pole
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. The jump line is triggered at high level when it is short -connected with HIGH.
