TWO CHANNEL 2 CH 12V ULN RELAY BOARD MODULE FOR IN INDIA

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 two (2) 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 hence your input device, such as Arduino, is protected from relay circuit and Transistor will further protect your micro-controller 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.  - BC 547 Transistor 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
