Allen-Bradley 849-ZOD32 Pneumatic Time Delay Relay is an on-delay timing device in the 849 family that introduces a controlled pneumatic delay between an input signal and its output, using a synthetic rubber bellows for timing. It is powered by 110/120 VAC at 50/60 Hz and is designed for industrial control circuits where a precise, repeatable delay is required to sequence valves, actuators, or other loads. The ZOD32 suffix identifies this particular on-delay pneumatic variant within the 849 series, a design that delivers timing action through a pneumatic mechanism rather than electronic timing circuitry. Current catalog listings note this model as discontinued.
