Allen-Bradley 700-HR52TA17 Relay

Allen-Bradley 700-HR52TA17 is a general-purpose dial timing relay (tube-base style) in the 700-HR family, delivering precise, adjustable delays with two timed changeover contacts for compact control circuits. The device is multi-function with six timing modes, enabling a wide range of applications from short delays to long interlocks, with timing ranges from 0.05 seconds to 300 hours. It provides two timed contacts (DPDT) and features no separate voltage inputs for the timing function, meaning the timer is activated by energizing the coil according to the specified power rating. The model supports coil voltage options of 100–240 V AC at 50/60 Hz and 100–125 V DC, allowing compatibility with common control power supplies. Designed for panel or socket-base installation, this timer relay is well-suited for sequencing, timer-controlled holding circuits, and interlock schemes in automation panels. Its dial-adjustable timing, combined with two Form C outputs, lets you drive auxiliary relays, solenoids, or signaling devices with repeatable precision. Typical applications include motor-start delays, timed signaling, and light-to-medium duty sequencing in industrial control where a compact, adjustable timer is advantageous.
