Allen-Bradley 849-Z0D32 Pneumatic Timing Relay

Allen-Bradley 849-Z0D32 Pneumatic Timing Relay is a Series B Bulletin 849 timing relay that provides an adjustable pneumatic time delay for industrial control circuits. This device uses a pneumatic mechanism with a synthetic rubber bellows and features a screw-type needle valve to regulate air flow, enabling precise timing adjustments without electronic timing components. It is designed to coordinate sequencing and delayed actuation in automation equipment such as presses, conveyors, and other machinery where a reliable, mechanical delay is preferred. The 849 family is known for rugged, mechanical timing suitable for panel-mounted installations in industrial environments, and the 849-Z0D32 designation identifies a specific Series B configuration within that lineage.
