This is a 5V, Single Channel Relay interface board; it’s useful to control various appliances, and other equipment’s with large current. It can be controlled directly by any Micro-controller (Raspberry Pi, Arduino, 8051, AVR, PIC, ARM, DSP, MSP430).
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) onboard relay which can switch upto 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 BC547 hence your input device, such as Arduino, is protected from the relay circuit. It serves as an optocoupler isolation board.
Technical Specifications:
- Control voltage: 5V
- Channels: 4
- Drive Current: 15-20mA
- Relay Ratings: AC250V 10A ; DC30V 10A
- Indication LED’s for Relay output status
Package Includes:
- 1 Piece- 4 Channel Isolated 5V 10A Relay Module Optocoupler
| Weight | 55 g |
