Adjustable Timer Kit – 9v Relay

Description

This single relay is controlled by a PIC microprocessor that has one trimmer for adjusting the relay “ON” time from 1 second to 4 minutes and it has another trimmer for adjusting the relay “OFF” time from 1 second to 4 minutes. This will allow you to have various different duty cycles.

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.

The relay contacts are rated for 7 Amps @ 125VAC. The contacts are Form C with COM, NO & NC outputs available. There is a LED on board that comes on whenever the relay comes on. The input power is 9v. The relay coil is 9v. 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.
