Yizhet 8 Channel DC 5V DC 230V Relay Shield Module Control Board with Optocoupler for Raspberry Pi DSP AR PIC ARM TTL Logic (5V 8 Channels)

Description

5V 8-channel relay module！Technical specifications:Product size: 138 * 55 * 17mmNumber of relays: 8Control current: 15-20mARelay type: changeover switchSupply voltage (VCC): 5 V.The relays used can switch up to AC 250V 10A or DC 30V 10A.Properties:➤Can be controlled directly via a microcontroller. Optocoupler inputs➤Status LEDs for relay output➤Can be controlled directly with 5V from the microcontroller! (Raspberry Pi, Arduin, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic.)➤ Small dimensions, large capacity: the relay can be mounted on a small PCB board and it can withstand high currents up to 10A➤ Widely used for home appliance, office machine, audio, equipment, automobile, etc. (Other applications: remote control TV receiver, monitor display, high power usage audio device.)What does the jumper cap do when connected to DJ-VCC?Used to supply the part of the relays with the same VCC as the optically isolated part.If you want to disconnect the power supplies, remove the bridge and connect the external power supply between JD and GND without connecting the Arduin GND.After removing the jumper cap, you need to power the JD-VCC separately.Wiring:IN1, IN2, IN3, IN4, IN5, IN6, IN7, IN8: relay control connectionsVCC: power system positiveGND: power supply system negativeJD-VCC: Relay Power SupplyScope of delivery:2x 8 channel relay module
