2 channel relay module 2-way relay expansion board 5V

Description

The relay module described features two channels, each capable of switching a load with a maximum capacity of 250V at 10A. The relay outputs have both normally open and normally closed terminals, with their activation being governed by a low signal input, compatible with voltages ranging from 0V to 5V. The system power, labeled as VCC, operates at 5V, while JD-VCC specifically powers the relays. By default, the relays are designed to function at 5V. Notably, the JD-VCC and VCC terminals are intended to be connected together.

In practical terms, this relay module allows for the control of external devices or circuits using low-voltage signals within the specified range. The dual-channel configuration offers flexibility in managing multiple loads or circuits simultaneously. The relay contacts provide options for both normally open and normally closed configurations, catering to different application requirements. With a maximum switching capacity of 250V at 10A, it can handle a wide range of electrical appliances or systems. The 5V operating voltage simplifies integration with microcontroller-based systems commonly used in automation and control applications. Overall, this relay module provides a versatile and reliable solution for switching high-power loads in various electronic projects or industrial applications.
