The Omron LY4-D DC24 is a 4PDT (four-pole double-throw) general-purpose relay from the LY series, with a 24V DC coil and socket-mount packaging. The 4PDT contact arrangement gives you four independent switching channels in one relay body — useful for controlling multiple circuits (e.g., separate signal and power paths) from a single coil command. Contact ratings are 10 A at 120V AC and 10 A at 24V DC, so it handles moderate loads like small motors, solenoids, or pilot lights directly without an interposing contactor. The 14-pin pinout matches standard LY-series sockets (e.g., Omron PTF14A), so panel wiring stays consistent across the family. The 1/2 hp rating at 240V AC confirms it can switch fractional-horsepower single-phase motors up to that size — useful for small pumps, fans, or conveyor drives in control panels. Electrical operating durability is rated at 200,000 operations, and mechanical durability at 50,000,000 to 100,000,000 cycles, meaning the mechanical life far exceeds the electrical life under load; plan replacement based on switched current and frequency, not just cycle count.

Frequently asked questions
How do I get current pricing and availability for LY4-D DC24?
Pricing and stock are confirmed at quote time. Submit an RFQ for the LY4-D DC24; the part is sourced to order through independent distribution, and current availability will be provided with the quotation.
What is LY4-D DC24's series and contact configuration?
The LY4-D DC24 belongs to Omron's LY series. It has a 4PDT (four-pole double-throw) contact form with 14 pins, socket-mount style, and a 24V DC coil.
What are the contact ratings of LY4-D DC24?
The contacts are rated 10 A at 120V AC and 10 A at 24V DC, with a motor rating of 1/2 hp at 240V AC.
Will LY4-D DC24 drop into a panel specified around MY2ZN-D2 DC24 without rewiring?
No — the LY4-D DC24 uses a 14-pin socket (4PDT), while the MY2ZN-D2 DC24 uses an 8-pin socket (DPDT). The pinouts and footprint differ, so the panel would need rewiring and a different socket.
