Overview
The Allen-Bradley 700-HT12AU24 is a tube base timing relay designed for on-delay applications in industrial control and automation systems. This DPDT (Double Pole Double Throw) relay is rated for 24V AC/DC operation and provides adjustable timing between 0.1 and 10 seconds, making it suitable for a wide range of timing-critical processes. Its rugged construction and pin-style socket mounting ensure reliable performance in demanding environments.
Key Features
