12V Power On Delay Relay Module Delay Circuit Module NE555 Chip

Imported high quality delay chip design, the performance is far better than the 555 chip. Delay time range selection, the shortest 0.1 seconds, up to one hour, to meet most of the demand. Against power reversal protection diode, the effective protection of the product. Can be accessed by high current loads (AC 250V / 10A, DC 30V / 10A). Time delay adjustment potentiometer clockwise adjustment will be more long.
