User Guide: DC Motor Reverse Polarity Switching Module

Purpose:

This module is designed to reverse the polarity of a DC motor when a 12V signal is applied at the control input. It allows for controlled directional changes of small DC motors up to 24W.

Key Specifications:

• Control Power Supply: 12V DC
• Feeding Input:
  • DC: 1 to 24V
  • AC: 1 to 120V
• Output:
  • DC: 1 to 24V, up to 2A
  • AC: 1 to 120V, up to 1A
• Relay Specifications:
  • 24V DC: 2A (up to 24W motor)
  • 120V AC: 1A (up to 120W motor)
• Dimensions: 30mm x 29mm x 18mm
• Wire Length: 10 cm

Setup Instructions:

1. Connect Power:

   • Connect the feeding power supply to the input terminals, marked as "In" (red and black wires).
   • Ensure the feeding input voltage matches the motor’s operating voltage.
   • Follow polarity for DC inputs.

2. Connect the Motor:

   • Attach the motor to the output terminals labeled “OUT” (white wires).
   • The motor will run in one direction upon connection.

3. Control and Reverse Direction:

   • To reverse motor direction, apply 12V DC to the control input (yellow wires).
   • This will reverse the output polarity, changing the motor’s rotation.

Application Notes:

• Designed for small DC motors up to 24W.
• Ensure motor voltage matches feeding input voltage for optimal operation.
• Respect the maximum current ratings to avoid module damage.

This module provides reliable control for applications needing motor direction switching, making it ideal for simple automation tasks.
