2 Channel Relay Module Relay Board Arduino Relay Module With Optocoupler

Product details

2 Channel Relay Module Relay Board Arduino Relay Module. With Optocoupler allows a wide range of microcontrollers. Such as Arduino, AVR, PIC, ARM with digital outputs to control larger loads and devices like AC or DC Motors, electromagnets, solenoids, and incandescent light bulbs. 4 – channel relay interface board , and each channel needs a 15-20mA driver current. It can be used to control various appliance Specifications Of 2 Channel Relay Module Relay : 5V 2-Channel Relay interface board, and also each one needs 15-20mA Driver Current Equiped Equipped with high-current relay, AC250V 10A ; DC30V 10A Standard interface that can be control directly by microcontroller (Arduino , 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic active low) Opto-isolated inputs Indication LED’s for Relay output status Module interface Of 2 Channel Relay Module Relay: The positive (according to the relay voltage VCC: connect power supply) GND: connect power negative IN1: relay module (effective) high-level trigger signal trigger end IN2: relay module (effective) high-level trigger signal trigger end Meaning of High level and Low-level High-level trigger refers to using the anode voltage at the VCC connection way of a trigger. And triggers the end when the trigger side has the positive voltage or to trigger voltage when the relay is off. Low-level trigger refers to using the negative voltage at the GND connection way of a trigger and triggers the end when the trigger side has 0 v low voltage or voltage to can trigger, the relay is off.
