The Omron H3YN-4-Z-B DC24 is a 4PDT timer relay from the H3YN series, offering a timing range of 0.1 seconds to 10 minutes and operating on a 24 VDC supply. It's the kind of part you spec into a control panel when you need a reliable on-delay or interval timer for a conveyor interlock, a pump sequencing circuit, or a machine-cycle pause — no programming, just a potentiometer and a DIP switch to set the range.
The 4PDT contact arrangement gives you four independent form-C outputs — enough to switch a motor contactor coil, a pilot light, and a PLC input all from one timer. The 0.1 s to 10 min timing range covers most machine-cycle delays you'd see on a packaging or material-handling line. The DC24 coil draws about 0.2 A from the 24 VDC bus, so it won't strain a small power supply. No separate socket is included in the Bulk package; you'll need an Omron PF-series socket (PF083A or similar) to wire it into the panel.
