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.
Use advance and high quality clock chip, accurate timing; Use super power relay control load, maximum up to 30A; Opto-isolator trigger, anti-interference and avoid false triggering; High level or low level trigger option; With selectable 8 type time range: Min. 0.1s, Max. 1 hours; With potentiometer to adjust, time will prolong if adjust it clockwise; With indicator for power and time delay switch.
Widely use in machinery equipment, automation equipment DIY, PLC industrial control and 12V vehicle.
