Optocoupler-Isolated 2 Channel DC 5V Relay Module for Arduino Raspberry Pi MEGA 2560 DSP AVR PIC ARM MCU STM32 Electronic Experiment Smart Home Ind

This product is a 2-channel relay module board with LED indicators, It can be controlled by microcontrollers such as Arduino, Raspberry Pi,AVR, PIC, ARM with digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs. Features This relay module is 5V active low. Relay output maximum contact is AC250V 10A and DC30V 10A. Standard interface can be directly connected with microcontrollers. Opto-Isolated inputs, means your digital electronics is safe and noise free. It is an 2-channel relay interface board, which can be controlled directly by a wide range of microcontrollers such as Arduino, AVR, PIC, ARM, PLC, etc. It is also able to control various appliances and other equipment with large current. Widely used for all MCU control, industrial sector, PLC control, smart home control. Technical Specifications Control signal: TTL level Working voltage: 5V Channel: 2 channel Item weight: 29g Package weight: 32g Item size: approx. 4.9 * 3.8 * 1.7cm / 1.93 * 1.5 * 0.67in Documents and Downloads Relay Module Schematics can be downloaded from online Package Includes 1x Opto-isolated 2 Channel 5V Relay Module Pin Definition: COM - Common pin: This is source pin, that starts connected to NC, and connects to NO when you apply 0v / GND (active low) NC (Normally Closed): in which case NC is connected with COM when INT1 is set low and disconnected when INT1 is high; NO (Normally Open): in which case NO is disconnected with COM1 when INT1 is set low and connected when INT1 is high. INT 1- Relay 1 control port: changes from the COM–>NO to the COM–>NC when you apply 0v / GND (active low) INT 2- Relay 2 control port: changes from the COM à NO to the COM à NC when you apply 0v / GND (active low)
