Description

The module, when powered on, starts the timer immediately (time range is adjustable). The relay activates, switching the common terminal of the relay. At the end of the time delay, the relay deactivates, connecting the common and the normally closed terminal.

Features

• Imported high-quality delay chip design, superior to the 555 chip
• Delay time range selection from 0.1 seconds to one hour, catering to a wide range of needs
• Power reversal protection diode for effective product protection
• Handles high current loads (AC 250V / 10A, DC 30V / 10A)
• Time delay adjustment using a potentiometer

How It Works

When the module's trigger terminal senses a momentary switch closure, it initiates the delay time function, closing the relay. Once the delay ends, the relay returns to the normally closed terminal. If another trigger signal is received during the delay, timing restarts automatically.

Select the delay time using switch S1, S2, and S4, and adjust it with the potentiometer.

Applications

The module is suitable for a wide range of applications including:

• The tachograph GPS start protection
• Household appliances
• Electronic equipment protection
• Sound protection
• Industrial control
• PLC control
• Electronic experiments
• Robotics
