Two Digit Timer

Words Up Timer This project is a simple two digit timer that counts seconds as long as a set of external contacts (from a relay) are closed. It is intended for use in a video booth where it indicates the time in seconds that words (text) from a secondary video source have been displayed as an overlay on the main video signal. The timer is controlled by the video switch via a relay card in the video switch. A set of contacts from the video switch are closed as long as the secondary video source (text in this case) is overlaid on the main video. This allows the video switch operator to determine how long the text has been displayed.
