Description
This is a description of a time delay relay module board that operates on a 12V coil. It uses a high quality clock chip for accurate timing and a powerful relay to control loads up to 30A. The opto-isolator trigger helps prevent interference and false triggering, and there is an option for high or low level triggering. The module has 8 selectable time ranges, adjustable with a potentiometer, and includes indicators for power and time delay. It is suitable for use in machinery equipment, automation equipment DIY, PLC industrial control, and 12V vehicles.
