1 Channel Opto-Isolated Relay Module This 1 Channel Opto-Isolated Relay Module is a 5V, 10A 2-Channel Relay interface board. It can be used to control various appliances, and other equipments with large current. It can be controlled directly with 3.3V or 5V logic signals from a microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic). Features of 1 Channel Opto-Isolated Relay Module: Four weeks of the board with four screws holes, hole diameter 3.1mm, easy to install and fixed Relay made of high quality loose music relays SPDT. A common terminal, a normally open, one normally closed terminal Optocoupler isolation, good anti-jamming Low pull, high release. Energisation status indicator lights D1, D1 status lights off when you release VCC of system power, JD_VCC relay power. Default hair 5V relay, you can plug in jumpers Relay Maximum output: DC 30V/10A, AC 250V/10A Wiring: VCC: positive power supply system GND: System power negative IN1: relay control ports General Brand:Jtron Model:03100467 Quantity:1Piece Color:Black Material:Glass fiber plastic iron Specification English Manual / Spec:No Dimensions & Weight Dimensions :2.09 in x 1.1 in x 0.67 in (5.3 cm x 2.8 cm x 1.7 cm) Weight :0.78 oz (22 g) Package Include: 1 x 1-Channel 5V 10A Relay Module For Arduino PIC AVR DSP ARM Specification English Manual / Spec:No Dimensions & Weight Dimensions :2.09 in x 1.1 in x 0.67 in (5.3 cm x 2.8 cm x 1.7 cm) Weight :0.78 oz (22 g) Package Include: 1 x 1-Channel 5V 10A Relay Module For Arduino PIC AVR DSP ARM Specification English Manual / Spec:No Dimensions & Weight Dimensions :2.09 in x 1.1 in x 0.67 in (5.3 cm x 2.8 cm x 1.7 cm) Weight :0.78 oz (22 g) Package Include: 1 x 1-Channel 5V 10A Relay Module For Arduino PIC AVR DSP ARMrduino PIC AVR DSP ARM
