100% brand new and high quality. Power on, equipment delay a certain time before power on until power disconnects. Or power on equipment to work immediately, delay time, automatically stops. This product is a new digital LED countdown display 12V delay module. It can be widely used with various control switch locations. Products can set the delay time, can press the "set" buttons. After installation, the power-on value is the previous set delay time that we set last time (memory function upon power failure). Products are precision delay, error 0.01% per second, a delay of 0-99 seconds, LED changes per second. The wide range of products can be used in many fields. Products work in low-power mode, press the left button to turn off the digital display or start displaying. Products with high-current input voltage regulator chip, with optoisolated output, improved anti-jamming capability and ensures stability. Increase the power supply's anti-reverse function. Voltage: Voltage DC 12V. Inputs and outputs are optoisolated, improved anti-jamming capability. Power: Quiescent current: 20mA. Working current: 50mA.
