A relay is an electrically operated switch. Many relays use an electromagnet to mechanically operate a switch, but other operating principles are also used, such as solid-state relays. Relays are used where it is necessary to control a circuit by a separate low-power signal, or where several circuits must be controlled by one signal.

OVERVIEW

This is a 5V 1-Channel Relay Module board, Be able to control various appliances, and other equipment with large current. It can be controlled directly by Microcontroller (Raspberry Pi, Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). Very useful project for application like Micro-Controller based projects, Remote controller, Lamp on Off, and any circuits which required isolated high current and high voltage switching by applying any TTL or CMOS level voltage.

FEATURES

High current relay, AC250V 10A, DC30V 10A

1 LED to indicate when relays are on

PWR LED indicator

Works logic level: 5V

Opto isolation circuitry

INPUT

It has a 1*3(2.54mm pitch) XH2.54 header for connecting power (5V and 0V), and for controlling the relay. The pins are marked on the PCB:

GND – Connect 0V to this pin.

VCC – Connect 5V to this pin. Is used to power the opto couplers

SIG – Controls relay, you can select high level active or low level active through the jumper on the pcb board

OUTPUT

This relay module could be considered like a series switches: 1 normally Open (NO), 1 normally closed (NC) and 1 common Pin (COM).

COM- Common pin

NC- Normally Closed

NO- Normally Open
