Allen-Bradley 849-ZOD32 is a pneumatic time-delay relay (on-delay) from the Bulletin 849 family, used to introduce a controlled delay after an input signal before the output operates. It is designed for 110/120 VAC power supplies at 50/60 Hz and employs a pneumatic timing chamber with a synthetic rubber bellows to establish the delay. The ZOD32 variant identifies the on-delay timing configuration within this lineage, providing a compact solution for timing and sequencing tasks in older industrial control panels.
