Descriptions: 8 Chanel 5v Realay Module
·This is a 5V 8-Channel Relay interface board, Be able to control various appliances, and other equipments with large current. It can be controlled directly by Micro-controller (8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic) .
A Relay is a digital switch to control much higher voltages and currents than your normal Arduino boards does. When inputs a logic voltage, the relay will switch to allow current to flow or cutoff, depending on your wiring. A Relay usually consists of a coil, 1 common terminal, 1 normally closed terminal and one normally open terminal. When the coil is energized, the common terminal and the normally open terminal will have continuity.
- This 8 channel 5V relay has both optical and magnetic isolation, providing a lot of protection to the inputs from electrical faults on the outputs.
- Works well with both 3.3V and 5V logic (Raspberry Pi, Arduino, Teensy..), requiring little current drive.
- Breadboard friendly, using Female/male dupont makes it extremely convenient for prototyping.
- LED indicates its working status. Red refers to errors.
- 3 terminals per SPDT relay.
