<b>Introduction</b> <br>Keyestudio RPI 4-Relay Shield works with Raspberry Pi A+/B+/Pi 2 Model B/Pi 3 Model B. This shield uses SONGLE relay, providing 4-channel input and output. The relays are isolated in the PCB. <br>All the channels can control up to 24V DC or 250V AC on 10 A. It allows you to control high power components like lights and motors via Raspberry Pi 3. <br>Just plug it directly into your pi with 5 V. You will find a LED indicates the status of the relays that an indicator to check working state easily. <br>It can be applied to high voltage filed like home automation.With opto-asolator to avoid disturb of high voltage. <br> <br>We will provide installation package, source code and quick start guide PDF on keyestudio wiki page. <br>http://wiki.keyestudio.com/index.php/KS0212_keyestudio_RPI_4-channel_Relay_Shield<br> <br><b>Specification</b> <br>Control Signal: TTL Level <br>Rated Load： <br>10A 250VAC <br>10A 125VAC <br>10A 30VDC <br>10A 28VDC <br>Rated Current: 10A(NO)  5A(NC) <br>Max Switching Voltage: 250VAC  30VDC <br>Contact Time: under 10ms<br> <br> <b>Application: </b> <br>Smart home control <br>PLC control<br> <br><b>Shipping list:</b> <br>4-channel 5V Relay*1pcs <br>M2.5 nut *4pcs <br>M2.5*10 copper pillar*4pcs <br>M2.5*20MM round head screw*4pcs
