12V 2 channel relay module with light coupling

12V 2 channel relay module with light coupling

This is a 2 channel 12V relay module with light coupling. This board is manufactured from a new and advanced design with high-end SMT processors. The terminals (C, NC, NO) are accessible through screw terminals which makes wiring up the board very easy. The relay is safely driven by transistor BC547 hence your input device, such as Arduino, is secure from the relay circuit. The inputs of this module are isolated to protect any delicate control circuitry.It can be controlled by a variety of microcontrollers such as Arduino, AVR, PIC, ARM, etc. Using a high-voltage relay eliminates the risk of the relay overheating because the electromechanical relay limits power consumption based on the rated voltage.

Features:-

• Equipped with high-current relay
• It is capable of managing both AC and DC appliances, including fans, lights, and motors.
• High-quality screw terminals
• Freewheeling diode to protect your microcontroller
