5v 1 Channel Relay Module for Arduino ARM PIC AVR MCU DSP Raspberry Pi Relay Expansion Board Shield with Indicator LED

The Arduino 5V relay module is suitable for SCM development, home appliance control. It is with 5V~12V TIL control signal which can control DC / AC signal. The module is perfect for common Arduino application. Features The features of 1-Channel Relay module are as follow: 1) Good in safety.In power system and high voltage system, the lower current can control the higher one. 2) 1-channel high voltage system output, meeting the needs of single channel control 3) Wide range of controllable voltage. 4) Being able to control high load current 5) With a normally-open (NO) contact and a normally-closed (NC) contacts Description: 5V DC 1-Channel Relay Module for Arduino Trigger mode: High level Relay:SRD-5VDC-SL-C Color: Blue + Black Size of PCB:1.375"(3.5cm)long, 1" (2.5cm) wide,extends 0.75" (1.7cm)above the board 5V TTL controlled signal LED Power indicator Normally open / closed contact Can control DC or AC signal, also 220V AC load Controlled light is on when pulled up and off when disconnect Increase the transistor drive relay coils, control pins high impedance Control pins have pull down circuit to prevent malfunction of relay vacant Can be used for microcontroller development board module or home appliance control Application: .Useful to control a motor, a led strip, or any other module using arduino .Suitable for SCM development, home appliance control .Using to turn on a heated bed on a 3D printer How to use it: Just connect a digital output of your arduino to your relay module, and you can control a power-demanding appliance with the digital signal provided by your arduino Note:Make sure wires don't get tugged out of terminals Package included: 1 x 5V 1 channel relay module
