Overview
The Allen-Bradley 700-HR52TA17 is a tube base dial timing relay manufactured by Rockwell Automation for demanding industrial control applications. This multi-function relay delivers six selectable timing modes and a wide timing range from 0.05 seconds to 300 hours, making it suitable for both fast-response and long-duration timing sequences. The 11-pin plug-in design enables straightforward socket or panel mounting in standard relay bases.
Key Features

Typical Applications
The 700-HR52TA17 is widely used in industrial automation and control systems including:
- Machine startup and shutdown sequencing with time-delayed logic
- Process control timing for batch operations, conveyor systems, and material handling
- Pump and motor protection circuits requiring on-delay or off-delay functions
- HVAC system timing and interlocking applications
- Alarm and monitoring circuits with adjustable delay periods
- Safety interlocks and dwell-time control in manufacturing environments
Compatibility & Replacements
Compatible With
- Allen-Bradley timing relay sockets and base modules
- Standard industrial control relay racks and enclosures
- 24VDC and 120VAC control circuits (via appropriate voltage inputs)
- Rockwell Automation control panels and distribution systems
- Legacy and modern industrial automation installations
Replaces / Drop-In Replacement For
Verify specific cross-reference requirements with your system integrator or controls engineer, as timing relay compatibility depends on coil voltage, contact configuration, and mounting style. The 700-HR52TA17 may replace earlier-generation dial timing relays with equivalent DPDT contact arrangements and voltage ratings.
Works With
- Allen-Bradley PLC and PAC systems via relay-based control logic
- Direct hardwired control circuits (no software required)
- Legacy industrial control systems and pneumatic timing applications
- Standard 11-pin relay sockets and mounting bases
- Auxiliary relay contact blocks and interlocking modules
