This board has one (1) on-board relay which can switch up to 7amps. Relays terminals (c, nc, no) are accessible through screw terminals which makes wiring up the board very easy. The relay is safely driven by transistor bc547 hence your input device, such as arduino, is protected from relay circuit. There is free wheeling diode which will further protect your microcontroller from relay kick back. This is a 12v 1-channel relay interface board which can be controlled directly by a wide range of microcontrollers such as arduino, avr, pic, arm, 8051 and so on. ## Technical Specifications | Specification | Value | |---------------|-------| | Connector Type | Screw | | Current Rating | 7 Amps | | Mounting Type | Screw Mount | | Brand | Elementz Engineers Guild Pvt Ltd | | Operation Mode | Automatic | | Coil Voltage | 12 Volts | | Contact Current Rating | 7 Amps | | Maximum Switching Current | 7 Amps | | Manufacturer | Elementz Engineers Guild Pvt Ltd | | Model number | 1CH_RELAY_BOARD | | Number of Memory Sticks | 1 | | Item Weight | 20 g | | Package Dimensions | 11.6 x 6 x 1.6 cm; 20 g | | Item model number | 1CH_RELAY_BOARD | | Are batteries included? | No | ## Images ![Elementz Engineers Guild Pvt Ltd 1CH_RELAY_BOARD One Single Channel 1 Ch 12V Relay Board Module, Controllable with 5V Or 3.3V Signal - Image 1](https://m.media-amazon.com/images/I/91yl8bLuApL.jpg) ![Elementz Engineers Guild Pvt Ltd 1CH_RELAY_BOARD One Single Channel 1 Ch 12V Relay Board Module, Controllable with 5V Or 3.3V Signal - Image 2](https://m.media-amazon.com/images/I/914vuQB7fNL.jpg) ![Elementz Engineers Guild Pvt Ltd 1CH_RELAY_BOARD One Single Channel 1 Ch 12V Relay Board Module, Controllable with 5V Or 3.3V Signal - Image 3](https://m.media-amazon.com/images/I/91Z9QxK++3L.jpg) ![Elementz Engineers Guild Pvt Ltd 1CH_RELAY_BOARD One Single Channel 1 Ch 12V Relay Board Module, Controllable with 5V Or 3.3V Signal - Image 4](https://m.media-amazon.com/images/I/410sT0fYztL.jpg) ![Elementz Engineers Guild Pvt Ltd 1CH_RELAY_BOARD One Single Channel 1 Ch 12V Relay Board Module, Controllable with 5V Or 3.3V Signal - Image 5](https://m.media-amazon.com/images/I/61U8havgMhL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Awesome product to buy for beginners *by S***A on Reviewed in India on 8 November 2016* I am using this product since last 4 months.
