0.5–10 s hand-dial, on-delay or off-delay in one socket
The H3Y-2 AC200-230 10S is Omron's H3Y series electromechanical time-delay relay built around a DPDT (2 Form C) mechanical relay contact set, with the delay adjustable from 0.5 Sec to 10 Sec on the front-face hand dial and the same unit capable of either off-delay or on-delay timing on application choice. That 10-second upper window makes the part the typical fit for short-cycle sequencing on packaging and machine-tool control panels — interlock delays, lubrication or pneumatic purge timers, and pump no-flow watchdogs — where a one-second-grade electronic timer would be over-specified and a motor-driven cam timer would be over-built.
Coil and contact ratings for control-panel service
The supply input is 200 ~ 230VAC and the timing initiate method is input voltage, so the timer is wired directly across the control transformer secondary with no separate DC rail — the relay closes or opens at the end of the dial-set interval based on whether on-delay or off-delay is selected. The DPDT contact set is rated 5A at 250VAC, which is the usual ceiling for switching small contactor coils, solenoid valves, and indicator lamps inside a control panel; the contact rating, not the supply voltage, is what governs how much load the timer can directly commutate and whether an interposing relay is needed downstream.
Plug-in 11-pin socket and panel footprint
Mounting is socketable with a Plug In termination, the standard H3Y form-factor that drops into an 11-pin octal base already on the DIN rail of an existing panel — the swap is a pull-and-replace on the base, not a rewire, which keeps retrofits on the H3Y line low-risk for panel builders standardising on that footprint.
Lifecycle read for the maintenance spare
Omron lists the H3Y-2 AC200-230 10S as active in catalog and a mature product line, meaning the part is still factory-current and supported for production runs while older variants in the series have been pruned — for a maintenance buyer that translates to a quoted-to-order supply posture from independent distribution with no last-time-buy urgency on this specific code.
