Allen-Bradley 849-ZOD1231 Pneumatic Timer

Allen-Bradley 849-ZOD1231 Pneumatic Timer is a 849-series pneumatic timing relay used to introduce timed delays in industrial control circuits. The unit is rated for 10 A at 110 VAC, 60 Hz, enabling it to energize or de-energize standard control devices such as contactors and relays as part of machine sequencing and automated start/stop routines. As a member of the Rockwell Automation/Allen-Bradley family, this timer relies on a mechanical pneumatic timing mechanism rather than electronic timing, delivering repeatable delay actions suitable for rugged industrial environments. Catalog number 849-ZOD1231 identifies this specific model within the 849 timer line, which is commonly employed for sequencing conveyors, coordinating pump starts, and other automation tasks where a timed output is required to ensure proper process flow.
