Overview
The Allen-Bradley 700-HT12AU120 is a tube base timing relay engineered for general-purpose industrial control applications. This time delay relay delivers reliable on-delay timing functionality with a 120V AC/DC coil rated for 50/60 Hz operation. The compact plug-in design integrates directly into pin-style socket mounts, making it a drop-in solution for legacy and modern control panels.

Typical Applications
The 700-HT12AU120 suits equipment sequencing, motor start delay, pump control, compressor staging, solenoid coil protection, and general timing control across manufacturing, food processing, material handling, and facility automation. Its rugged design and proven Allen-Bradley quality make it ideal for retrofit installations where legacy relay sockets remain in service.
Compatibility & Replacements
The 700-HT12AU120 is part of Allen-Bradley’s established 700-HT timing relay family and is compatible with standard 8-pin tube base sockets. For off-delay timing applications, consider the 700-HT22 series. When upgrading to solid-state alternatives, Rockwell Automation offers CompactLogix and PLC-based timing functions. Contact your distributor to confirm socket compatibility or discuss alternative timing relay configurations for your control requirements.
