Relay Module

<p>One module description:</p>
<p>1. The module adopts genuine high -quality relay.<br />
2. Using patch optocouplery isolation, strong driving capacity, stable performance; 5mA touch current;<br />
3. The working voltage of the module is 12V;<br />
4. The module can be triggered by high levels or low levels through the jump line;<br />
5. Fault tolerance design, even if the control line is broken, the relay will not move;<br />
6. Power indicator light (green), relay status indicator (red)<br />
7. The interface design is humane, and all interfaces can be led directly through the wiring terminal, which is very convenient.<br />
8. Module size: 50mm* 26mm* 18.5mm (length* width* height)<br />
9. There are 4 fixed bolt holes, a hole of 3.1mm, and a distance of 44.5mm*20.5mm<br />
Two module interface:<br />
1. DC+: The positive pole of the power supply (voltage according to the requirements of relay, 12V)<br />
2. DC-: The negative pole of the power supply<br />
3. IN: Can control relay suction and combination at high or low levels<br />
Relay output end:<br />
1. NO: relay often opens the interface, relay sucks the front suspension, and shortly with COM after suction<br />
2. COM: Public interface of relays<br />
3. NC: The relays are constantly closed interface, the relay is short -connected before the combination</p>
<p>High and low level trigger selection end:</p>
<p>1. The jump line is triggered at a low level when it is short -connected;</p>
<p>2. The jump line is triggered at high level when it is short -connected with HIGH.</p>
