2 Channel Relay Module Relay Board Arduino Relay Module With Optocoupler

Description

2 Channel Relay Module Relay Board Arduino Relay Module With Optocoupler in Karachi

Specifications:

1. 5V 2-Channel Relay interface board, and also each one needs a 15-20mA Driver Current
2. Equipped Equipped with high-current relay, AC250V 10A; DC30V 10A
3. Standard interface that can be controlled directly by microcontroller (Arduino, 8051, AVR, PIC, DSP, ARM, ARM, MSP430, TTL logic active low)
4. Opto-isolated inputs
5. Indication LED’s for Relay output status

Module interface:

• 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

A high-level trigger refers to using the anode voltage at the VCC connection as a trigger. It triggers the end when the trigger side has a positive voltage or triggers 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.
