2 CHANNEL RELAY MODULE

2 CHANNEL RELAY MODULE

The 2 Channel Relay Module with Optocoupler is a versatile component designed to control high-power devices through
low-voltage signals from microcontrollers such as Arduino, AVR, PIC, ARM, and others. Each channel 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.
