Description:
The 5V 4 Channel Relay Module with Optocoupler is a versatile interface board designed to control high-current loads using low-voltage signals from microcontrollers such as Arduino, AVR, PIC, ARM, and others. Each of the four channels is equipped with a high-current relay capable of handling up to 10A at 250VAC or 30VDC, making it suitable for managing various appliances and equipment. The inclusion of optocouplers ensures electrical isolation between the control and load circuits, enhancing safety and preventing interference.
This module features both normally open (NO) and normally closed (NC) contacts for each relay, providing flexibility in control configurations. Indicator LEDs for each relay channel offer visual confirmation of the relay’s status, facilitating easy monitoring during operation. The module’s standard interface allows for direct control by microcontrollers, simplifying integration into projects involving home automation, industrial control systems, and robotics.
