Four 12v

Product Overview Relay board module is used for controlling higher current loads from your microcontroller development board, PC parallel port or Arduino Uno. This board has four (4) 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 ULN IC hence your input device, such as Arduino, is protected from relay circuit and IC will further protect your microcontroller from relay kick back. This is a 12V 4-Channel Relay interface board which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, and so on.  - ULN IC used to drive Relays (better than Transistor Drive Circuits) - 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 - Input Signal Pin connected to Burg stick for easy accessibility - LED Status indicators to indicate the relay ON/OFF status. - Mounting holes provided

Description Four Channel 12V Relay Board: A relay is an electrically operated switch. Current flowing through the coil of the relay creates a magnetic field which attracts a lever and changes the switch contacts. The coil current can be on or off so relays have two switch positions. Relays are used where it is necessary to control a circuit by a low-power signal (with complete electrical isolation between control and controlled circuits), or where several circuits must be controlled by one signal. The board has FOUR relay which works on 12V but the input signal can come directly from microcontroller output working at 3V or 5V to control relays. Each relay can switch varierty of AC or DC high voltage, high current loads working at 110V or 220V AC mains like lights, fans, motors and such. The status of relay is indicated by the RED Led. This is a 4 channel relay board operates on 12V. Can be used directly to control 240V power appliance from most of the microcontrollers and other control system circuits. Perfect for switching 240V appliances like lights, fans, etc. The board has a high quality relay, which can handle a maximum of 10A @ 120V or 7A @ 240V AC. Each Relay has three connections - Common - C, 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 and a relay status LED to ease debugging. Power input and relay control signals are brought to header pins on the board. Features: Selectable Port Input Mounting Supports Provided Relay Switching Output Suitable for 7A @ 250Vac or 10A @ 120Vac LED Indication of Relay ON. Power Indication LED. Direct input from 3-5V Microcontroller for relay control. Output terminal for relay contacts. Provision of male header for wire connection. Powered from external 12V or from male header. Note: It is important that microcontroller share ground with relay board along with other control signals else it will not able to control relay.

HT12E & HT12D Encder / Decoder ICs + 2 X 18 Pin IC Base Combo... *** MUST HAVE FOR STUDENTS  AND HOBBYIST ***  The HT 12E   Encoders are a series of CMOS LSIs for remote control system applications. They are capable of encoding information which consists of N address bits and 12 N data bits. Each address/ data input can be set to one of the two logic states. The programmed addresses/data are transmitted together with the header bits via an RF or an infrared transmission medium upon receipt of a trigger signal. The capability to select a TE trigger on the HT12E or a DATA trigger on the HT12A further enhances the application flexibility of the 2 12  series of encoders. The HT12A additionally provides a 38kHz carrier for infrared systems.     The HT 12D   Decoders are a series of CMOS LSIs for remote control system applications. They are paired with Holtek s HT 12E series of encoders (refer to the encoder/decoder cross reference table). For proper operation, a pair of encoder/decoder with the same number of addresses and data format should be chosen. The decoders receive serial addresses and data from a programmed HT 12E series of encoders that are transmitted by a carrier using an RF or an IR transmission medium. They compare the serial input data three times continuously with their local addresses. If no error or unmatched codes are found, the input data codes are decoded and then transferred to the output pins. The VT pin also goes high to indicate a valid transmission. The HT 12D series of decoders are capable of decoding informations that consist of N bits of address and 12N bits of data. Of this series, the HT12D is arranged to provide 8 address bits and 4 data bits, and HT12F is used to decode 12 bits of address information.
