AOICRIE 3pcs 2 Channel DC 5V Relay Module for R3 DSP ARM PIC AVR STM32 for Raspberry Pi with Optocoupler Low Level Trigger Expansion Board
$29.99
- This is a 2 Channel 5V Relay with Optocoupler, LOW Level Trigger expansion board, be able to control various appliances, and other equipments with large current. Standard interface that can be controlled directly by microcontroller ( 8051, AVR, PIC, DSP,ARM, ARM, MSP430, TTL logic).
- Relay of high quality low noise relays SPDT. A common terminal, a normally open, one normally closed terminal.
- OptoCoupler isolation, for high voltage safety and prevent ground loop with microcontroller.
- VCC and JD-VCC are also the power supply of the relay module. When you need to drive a large power load, you can take the jumper cap off and connect an extra power to RY-VCC to supply the relay; connect VCC to 5V of the MCU board to supply input signals.
- LED light is used to indicate the relay output state; board four weeks with four screw holes, hole diameter 3.1mm, easy to install and fixed.
