وصف
This is a 5V Dual Channel Relay Module with Optocoupler for Arduino PIC ARM. It can be used to control various appliances and other types of equipment with a 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). This 5V Dual Channel Relay Module has a 1x4 (2.54mm pitch) pin header for connecting power (5V and 0V), and for controlling the 2 relays. The pins are marked on the PCB as: GND - Connect 0V to this pin. IN1 - Controls relay 1, active Low Relay will turn on when this input goes below about 2.0V IN2 - Controls relay 2, active Low Relay will turn on when this input goes below about 2.0V VCC - Connect 5V to this pin. Is used to power the optocouplers
Features :
2 LEDs to indicate when relays are ON.
Works with logic level signals from 3.3V or 5V devices
Opto isolation circuitry
Module with diode current protection, short response time
Around the board with 4 mounting holes, hole diameter 3. 1 mm, easy installation and fixing
