Description

This is a microprocessor-controlled PNP power transistor switch. It will accept a DC voltage from a power supply and will pass it thru to the output. The microprocessor will control how long the power switch is “ON” and how long it is “OFF”.

The Power Transistor is rated for 2 Amps of continuous duty with a DC Voltage input from 5vdc to 20vdc.

The “ON” and “OFF” times are adjustable via two independent variable controls. The times are adjustable from 2 seconds up to 4 minutes. This means that you can have it ON for 3 minutes and OFF for 1 minute and it will continue to cycle this way. The time adjustments can be made at any time while the device is powered.

For those with Microchip PIC programming experience, the PIC12F510 may be removed and re-programmed as desired. There are two DIP switches on board that are available for programming.

There is a LED on board that comes “ON” whenever the power transistor is “ON”. There is an onboard voltage regulator (5v) for the PIC microprocessor.

The PCB is 2.0″ x 2.5″, made out of .062″, FR-4, 2-Layer, 1-ounce copper.
