Timer Relay Module – Adjustable Time Delay Relay Switch

The Timer Relay Module is a versatile time delay control switch designed to trigger a relay output after a precisely adjustable time interval. Supporting multiple timing modes such as delay-on, delay-off, and cyclic ON/OFF operation, it is widely used in home automation, industrial control, and DIY electronics projects that require accurate timed switching of connected loads.

Key Features

Adjustable timing range from 0.1 seconds to 999 minutes
Four selectable working modes (P1 to P4)
Relay output supports up to 10A switching capacity
Opto-isolated input and output for enhanced noise immunity
Parameter memory retains last settings after power loss
Reverse polarity protection on power input
Industrial-grade PCB for reliable long-term operation
Compact size suitable for panel-mount or enclosure installation
Simple screw terminal connections for easy wiring
Easy integration with sensors, switches, and microcontrollers

Important Notes

Select the correct working mode (P1-P4) based on your application before use.
Do not exceed the rated relay output current of 10A; use an external contactor for higher loads.
Ensure trigger signal voltage stays within the specified 4V to 20V range for reliable operation.
Timing settings are retained in memory after power loss due to the built-in parameter memory function.
Use proper insulation and wiring precautions when switching AC mains loads.
Allow adequate ventilation if the module is enclosed, especially under sustained high-current switching.
