Description

  • Operation:
    • Control Signal: Activated by a low-power control signal typically from a microcontroller or digital logic circuit, triggering the relay to switch its contacts.
    • Relay Type: Electromechanical relay with a single pole, single throw (SPST) configuration, allowing it to control the connection of one circuit based on the control signal.
  • Features:
    • Coil Voltage: 12V DC coil voltage, suitable for operation with 12V DC power sources commonly available in electronic circuits and systems.
    • Contact Rating: Capable of switching loads with a specified current and voltage rating, typically ranging from a few amperes to tens of amperes at 12V DC.
    • Terminal Blocks: Equipped with screw terminals or pin headers for easy and secure connection of control signals, power supply, and load circuits.
  • Protection and Indication:
    • Built-in Protection: Includes protection features such as diodes or transient voltage suppression (TVS) devices to suppress back electromotive force (EMF) generated during relay switching, protecting the driving circuitry.
    • LED Indicator: Incorporates LED indicator(s) to provide visual feedback of relay activation, allowing users to monitor the relay’s operational status.
  • Applications:
    • Home Automation: Used in home automation systems for controlling lights, fans, appliances, and other electrical devices based on sensor inputs, timers, or user commands.
    • Industrial Automation: Integrated into industrial control panels and machinery for switching high-power loads such as motors, solenoids, valves, and heaters based on process variables or PLC commands.
    • Automotive: Employed in automotive applications for controlling relays in vehicle accessories, lighting systems, alarm systems, and power distribution modules.
    • Robotics: Utilized in robotics projects for controlling actuators, motors, grippers, and other mechanical components based on programmed sequences or sensor inputs.
  • Installation and Compatibility:
    • Mounting Holes: Features mounting holes or slots for secure installation onto a baseboard, chassis, or enclosure, facilitating integration into electronic systems and equipment.
    • Compatibility: Compatible with a wide range of microcontrollers, Arduino boards, Raspberry Pi, and other development platforms, offering flexibility and ease of use in various projects.
  • Considerations:
    • Load Specifications: Ensure that the relay module’s contact rating matches the electrical specifications of the load circuit, including voltage, current, and power requirements.
    • Coil Voltage Compatibility: Verify compatibility between the relay module’s coil voltage and the power supply voltage of the driving circuit to ensure proper operation and relay activation.
    • Driver Circuitry: Implement proper driver circuitry (e.g., transistor or optocoupler) between the control signal source and the relay module to provide isolation and protect the control circuitry from relay coil back EMF.
    • Environmental Conditions: Consider environmental factors such as temperature, humidity, and vibration when selecting and installing the relay module for reliable performance in various operating environments.
