User Guide: Module for Converting Constant ON Signal to Adjustable 0-10 Sec Single Pulse (12V)

Overview

This module is designed to convert a continuous 12V signal into a single 12V pulse with an adjustable duration, ideal for triggering devices that require momentary activation.

Features

• Input Signal: 12V DC (Red wire)
• Output: 12V single pulse (Yellow wire) with adjustable duration (0–10 seconds)
• Ground: Black wire
• Dimensions: 21 x 17 x 16 mm
• Time Adjustment: Adjusted with a trimmer (clockwise to increase pulse duration)

Wiring Instructions

1. Connect the Input Signal:

   • Red Wire: Connect to the continuous 12V DC signal.
   • Black Wire: Connect to ground.

2. Connect the Output:

   • Yellow Wire: Connect to the device requiring a single pulse signal.

Operating Principle

• Pulse Output:
  • When the red wire receives a 12V signal, the module outputs a single pulse through the yellow wire for the preset time.
  • Duration Adjustment: Use the trimmer to adjust pulse length (0–10 seconds).
  • Continuous Activation: Even if the input remains on, only one pulse is sent initially.
  • Restarting the Pulse: A new pulse is generated only when the input signal is restarted.

This module is useful for triggering actions that require a momentary signal despite a continuous input.
