Time Delay Relay for Panel Integration
The Omron H3Y-2 AC100-120 5M is a socketable time delay relay from the H3Y series, offering both off-delay and on-delay functions in a single DPDT (2 Form C) mechanical relay package. Its adjustable delay spans 0.2 minutes to 5 minutes, set via a hand dial on the top face — no programming tool needed. The 5A @ 250VAC contact rating handles pilot duty, small motor starters, and signal-level loads common in control panels. Powered by 100~120VAC, the timing is initiated by applying input voltage — a straightforward sequence for sequencing conveyors, pump alternation, or HVAC damper delays. The plug-in termination mates with standard 8-pin octal-style sockets, so replacement or initial wiring is a pull-and-plug operation on the DIN rail or panel surface.
