Allen-Bradley 700-NT Industrial Pneumatic Timing Unit

Allen-Bradley 700-NT Industrial Pneumatic Timing Unit is a pneumatic timer accessory for Bulletin 700‑N relays that provides ON‑delay timing through one normally open and one normally closed timed contact. Designed for use with 700‑N relays (2‑ to 4‑pole), the 700‑NT adds a dedicated pneumatic timing mechanism to control when contacts close or open in response to air pressure, independent of the relay coil. The unit offers a timing range of 0.2 to 60 seconds, enabling delayed actuation or de‑energization in control circuits. It is categorized under Timer controls and is intended to operate as part of the 700‑N family, delivering reliable delay functionality in rugged industrial environments. Typical applications include sequence control and interlocking in automated systems, motor start/stop delays, feeders, and cycle synchronization where a compact, non‑electrical delay element is advantageous.
