Convert Cyclic Pulse input to Constant Signal with delay 0–10s – 12V Automotive Module

It maintains a continuous output while the input signal is active and keeps the output running for a preset delay time (1–10 seconds) after the input signal is interrupted. If the signal resumes within the delay window, the module continues operation without interruption.

Key Applications

• Conversion of turn signal pulses to continuous output
• Sequential lighting control systems
• Automotive timing and signal stabilization
• Control of auxiliary 12V devices
• Signal delay and hold functions

Technical Specifications

• Supply Voltage: 12V DC
• Input Signal: 12V positive or negative pulse
• Output Voltage: 12V DC continuous output
• Adjustable Delay Time: 1–10 seconds
• Module Dimensions: 40 × 27 × 20 mm (with enclosure)

Wiring Description

Power Supply

• Red wire → +12V DC constant supply
• Black wire → Ground (–12V)

Input Signal (choose only one type)

• Orange wire → Positive trigger signal (+12V pulse)
• Brown wire → Negative trigger signal (–12V pulse)

⚠️ Only one input signal wire must be connected at a time.

Output

• White wire → +12V DC output
• Blue wire → Ground output (–12V DC)

Operating Principle

When powered, the module monitors the input signal.

• If a pulse signal is present, the module activates and maintains a continuous 12V output.
• The output remains active as long as the input signal is present.
• When the input signal is removed, the module keeps the output active for the preset delay time (1–10 seconds).
• If the input signal returns before the delay expires, operation continues without reset.
• If the input signal remains off longer than the set delay, the output shuts down and waits for a new trigger.

Time Adjustment

The delay time is set via onboard potentiometer:

• Clockwise rotation → decreases delay time
• Counterclockwise rotation → increases delay time
• Adjustment range: 1–10 seconds

Package Includes

• 1 × Signal Converter Module
• 1 × Instruction Manual and Wiring Diagram

Notes

• Designed for 12V DC automotive systems only
• Do not exceed specified input/output limits
• Incorrect wiring may damage the module
• Ensure proper insulation and secure connections during installation
