12 V Relay Module Single Channel

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.
