Allen-Bradley 1496-N1 Pneumatic Time Delay Relay

Allen-Bradley 1496-N1 Pneumatic Time Delay Relay is a complete, air‑actuated timing unit that introduces a precise electrical delay in a control circuit by using a pneumatic timing element. Equipped with two contacts—a normally open (NO) and a normally closed (NC) contact—this open‑type timing module handles up to 10 A at 600 V AC on non‑inductive loads, ideal for pilot‑duty signaling and sequencing in industrial machinery. The timing range spans from 1/20 second to 180 seconds, allowing operators to tailor the delay to conveyor cycles, presses, or valve actuation, without relying on electrical coils for timing. As part of the older Allen‑Bradley pneumatic timer family, the 1496‑N1 ships as a complete timing unit with a standard contact unit, designed to integrate with compatible control relays in open panel installations. Availability has varied over time, with distributors noting it as discontinued by the manufacturer, which may influence replacement options and compatibility with legacy systems. This device is suitable for applications requiring a simple, air‑timed delay in automated sequences, where a reliable, electrically isolated timing stage can drive downstream relays or valves in a safe, pilot‑duty configuration.
