1 Channel 5V Relay Module without 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.
• Direct Control: Unlike relay modules with optocouplers, this module directly interfaces with the control signal without optically isolating the input from the output. It is designed for applications where electrical isolation is not a primary concern.
• 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.
