4 CHANNEL 5V RELAY

The 4 channel 5v interface board is designed to control high voltage, high current load devices. In this relay interface board, each channel requires a 15-20mA driver current. This module is equipped with a high current relay of 10A @250 V AC/10A@ 30V DC. It consists of a standard interface that can be controlled by the microcontroller directly. And also led indication provided to indicate the status of the relay. The relay terminal Common(C), normally open (NO), normally closed NC) accessed through the screw terminals thus making wiring much easier. In this module, each relay can be ON/OFF by an optoisolated input that can be controlled by a microcontroller output pin.

This 5V 4-Channel Relay interface board is used to control various appliances and other equipment which requires a large current. This 5V RELAY is controlled directly by Microcontroller (for Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). This 4 Channel Relay Module provides connections for all 3 terminals of the relay i.e. NO, NC, and COM. There exist 2 LEDs on the relay module in which red indicates the status of the relay and green for power. When the input digital signal switches to high, the relay switched ON (closed), else remains to switch  OFF (opened). This module is also used to control various applications and equipment with a large current compliant with international safety.
