Overview
The Allen-Bradley 700-HR52TA17 is a tube base dial timing relay manufactured by Rockwell Automation for general-purpose industrial control and automation. This DPDT (Double Pole Double Throw) timing relay provides precise timing and delay functions across a wide range of industrial and process applications. The unit supports multi-function operation with six selectable timing modes and delivers timing accuracy within 0.2% of full scale.
Key Features
- Multi-Function Design: Six operating modes (A, B, B2, C, D, E, J) enable flexible timing configurations
- Dual Voltage Inputs: Compatible with 100-240V AC (50/60 Hz) or 100-125V DC power supply
- Extended Timing Range: 0.05 seconds to 300 hours for applications requiring both fast pulse control and long-duration delays
- DPDT Contact Configuration: Two independent timed contacts for simultaneous control of multiple circuits
- Tube Base Construction: Pin-style terminals designed for socket mounting (compatible with 700-HN100, 700-HN125, 700-HN108)
- 5A Pilot Duty Rating: Suitable for pilot-duty control circuits per NEMA B300 specifications

Typical Applications
The 700-HR52TA17 is ideal for machine automation, process control, and industrial delay circuits where:
- Precise time delays ranging from milliseconds to extended hours are required
- Multi-mode functionality enables one relay to replace multiple timing configurations
- Pilot-duty switching of 240V AC control circuits is needed
- Socket-mounted relays integrate into standard control panel layouts
- Both AC and DC power supplies must be supported in a single device
