Brand new and high quality <br />5V 4 channel relay module for PIC ARM DSP AVR electronic <br />1. Supply voltage: 5V<br />2. Drive level: 5V TTL drive level， was drived by high drive level <br />3. Suitable place: the occasion of small signal controlling large signal <br />4. Contact capacity ( controlled signal power ): DC 30V 10A or AC 250V 10A<br />5. Contactor: one normally open contactor， one normally close contactor<br />6. Indicator light: one power indicator light， two signal indicator light ( when connected， signal indicator light is on )<br />7. Drive circuit: triode drive circuit， controlling pin's high impedance only needs tiny drive current. ( about 5mA )<br />8. Relay controls signal drop-down， and prevent relay dangling triggered by mistake<br />9. PCB color: white PCB， simple and beautiful<br />10. PCB location hole: 3mm standard location hole， can install 3mm standard copper cylinder， screws.<br />1 x Relay module<br /><img src="http://img6.eachbuyer.com/x15/p25/ba845_1.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p25/ba845_2.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p25/ba845_3.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p25/ba845_4.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p25/ba845_5.jpg" />                                                        <img src="http://img6.eachbuyer.com/x15/p25/ba845_6.jpg" />
