2-Channel 5V Relay Module With Optocoupler for Arduino DSP AVR PIC ARM<br /><br />Module parameters: <br />1. Size: 50.6 x 39 x 19.3 mm <br />2. Weight: about 30g <br />3. PCB Color: black  <br />4. With 4 fixing screw holes, hole diameter at 3.1mm, easy to install and fix <br />5. Relay uses high quality song le relays, SPDT, one common terminal, one normally open, one normally closed terminal<br />6. Optocoupler isolation, good anti-jamming performance <br />7. Low level close and high level release. Status indicator turns on when closing and turns off when releasing. <br />8. VCC for system power, JD_VCC for relay power. Default as 5V relay, just plug the jumper cap <br />9. Maximum output relay: DC 30V / 10A, AC 250V / 10A<br /><br />Wiring instructions: <br />VCC: positive of power supply of system<br />GND: negative of power supply of system <br />IN1 - IN2: control port of relay  <br /><br />1 x Relay Module <br />In anti-static bag<br /><img src="//agdetail.image-gmkt.com/m430/691/596/560596691/img/agdetail.image-gmkt.com/691/596/560596691/img/img6.eachbuyer.com/x9/p100/eb3762_1.jpg" />                                                        <img src="//agdetail.image-gmkt.com/m430/691/596/560596691/img/agdetail.image-gmkt.com/691/596/560596691/img/img6.eachbuyer.com/x9/p100/eb3762_2.jpg" />                                                        <img src="//agdetail.image-gmkt.com/m430/691/596/560596691/img/agdetail.image-gmkt.com/691/596/560596691/img/img6.eachbuyer.com/x9/p100/eb3762_3.jpg" />                                                        <img src="//agdetail.image-gmkt.com/m430/691/596/560596691/img/agdetail.image-gmkt.com/691/596/560596691/img/img6.eachbuyer.com/x9/p100/eb3762_4.jpg" />                                                        <img src="//agdetail.image-gmkt.com/m430/691/596/560596691/img/agdetail.image-gmkt.com/691/596/560596691/img/img6.eachbuyer.com/x9/p100/eb3762_5.jpg" />
