Single Channel Relay Board Dealers

This is a small and easy to use 1 channel relay board that operates on 5V. Use it to control one 240V power appliance lights, fans, etc directly from microcontrollers or low voltage circuits. The relay can handle a maximum of 7A240 V AC or 7A24V DC. Relay has all three connections - Common(COM), Normally Open(NO), Normally Closed(NC) brought out to 3 pin screw terminals which makes it easy to make and remove connections. The board has a power indication (RED) and a relay status (GREEN) LED to ease debugging. The board can accept inputs within a wide range of voltages from 3V to 5V. Power input and relay control signals are brought to 3 pin header pins on the board. Hence, the board can be easily interface with our development boards using our female to female jumper wires.

Product ID: 1114 Relay board module is used for controlling higher current loads from your microcontroller development board, PC parallel port or Arduino Uno. 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.  

Relay Board allows you to control larger loads and devices like AC or DC motors, fans, light bulbs etc. Specifications: Reverse polarity and Back emf protection. Screw terminals for relay connections. Relay Board has an LED to indicate when relay is operated. Signal input for direct connection to Microcontroller, Arduino or any TTL output pins. Test Button for (without signal) Relay and load testing.

Equipped with high-current relay 7A@250VAC 10A@24VDC It can control both AC and DC appliances such as Solenoids, Motors, lights, fans, etc High quality screw terminals (Terminal Block) provided (C, NC , NO) for quick and easy connection Free wheeling diode to protect your microcontroller Input Signal Pin connected to Burg stick for easy accessibility LED Status indicators to indicate the relay ONOFF status Mounting holes provided

5V 4 Channel Relay Module Board For Arduino PIC AVR DSP ARM. Function: Support all single-chip microcomputer control Industrial circle PLC controller Household intelligent control, shock-resistant , industrial grade , superb workmanship, Ball Material Type-glass fiber pcb, Brand Name-Hindustan Mechano Solutions, Material Type-fiberglass printed circuit board.

The board has one relay which works on 5V but the input signal can come directly from microcontroller output working at 3V or 5V to control relays. Each relay can switch variety of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, and motors and such. The status of relay is indicated by the RED Led. FEATURES OF SINGLE CHANNEL 5V RELAY BOARD: LED Indication of Relay ON. Direct input from 3-5V Microcontroller for relay control. Output terminal for relay contacts. Provision of 2×3 pin male header for wire connection. Powered from external 5V or from male header. APPLICATIONS OF SINGLE CHANNEL 5V RELAY BOARD: Electromagnetic relays are employed for the protection of various ac and dc equipments. The over/under current and voltage protection of various ac and dc equipments. For differential protection. Device switching. Multiple DIY projects.
