Abstract
This project will use an Allen-Bradley SLC-150 microprocessor programmable controller to demonstrate an actual application being used in industry. The SLC-150 will be used to sequentially control a Pelco pan and tilt drive unit. This unit is mounted with a video camera that is used for security monitoring. The SLC-150 will also control the cameras zooming features.
Prior to microprocessors the electrical control of machines used input devices such as push buttons and limit switches connected to magnetically hard wired relay logic. Hard wiring meant that electrical wires were connected between all relay coils and contacts, making up what is known as relay logic. When the correct relay logic circuit were energized output devices such as Motor-starters and solenoids became energized
