1 Channel 5V Relay Module with Optocoupler

Description

• 1-Channel Relay: This module features a single relay channel, making it suitable for controlling one electrical circuit or load.
• 5V Operating Voltage: The module operates at a 5V input voltage, making it compatible with common microcontrollers and digital logic circuits.
• Optocoupler Isolation: An optocoupler (also known as an optoisolator) is integrated into the module. It provides electrical isolation between the control circuit (input side) and the load circuit (output side), enhancing safety and preventing voltage spikes from affecting the microcontroller.
• High Current Handling: The relay on the module can typically handle relatively high currents, making it suitable for controlling devices with moderate power requirements.
• Normally Open (NO) and Normally Closed (NC) Contacts: The module features both normally open (NO) and normally closed (NC) relay contacts. You can configure it to perform either latching or non-latching operations depending on your application.
• LED Indicator: A built-in LED indicator provides a visual indication of the relay’s state (on or off).
• Screw Terminal Blocks: The module typically includes screw terminal blocks for easy and secure connection of external wires, making wiring straightforward.
• Low-Level Trigger Input: The relay is activated with a low-level trigger signal, making it compatible with most microcontrollers and digital circuits.
• Versatile Applications: Suitable for various applications, including home automation, robotics, industrial control systems, DIY projects, and prototyping.
