Description: 1. A 12V 2-Channel Relay Board is an electromechanical switching device designed for controlling electrical loads through digital signals. It comes with two independent relay channels that can be operated individually or simultaneously. 2. Input Voltage: This board operates on a 12V DC power supply, making it suitable for use in various IoT projects and automation applications where low-voltage systems are prevalent. 3. Relay Specifications: Each channel features a NO (Normally Open) relay with an operating current of 10A and a maximum operating voltage of 35VAC/DC. These relays provide robust, reliable switching for controlling various electrical appliances and devices. 4. LED Indicators: Each channel comes equipped with an LED indicator light that displays the status of the relay (ON or OFF). This visual confirmation makes it easier to monitor and troubleshoot your IoT projects. 5. Diode Protection: The board incorporates diodes for reverse polarity protection, ensuring the rela
