Product details

Contact ratings and coil — what fits your load

The Omron LY4N-D2-DC24 is a 4PDT general-purpose relay from the LY series, socket-mounted with 14 pins. Coil pulls in at 24 V DC nominal.

Durability and dielectric — panel-builder notes

Electrical operating durability is rated 200,000 cycles; mechanical durability hits 50,000,000 to 100,000,000 cycles — the mechanical life far outruns the electrical, so in practice the contact load determines replacement interval. Dielectric strength: 1,000 V AC between same-polarity contacts, 2,000 V AC between coil and contacts or different-polarity contacts — standard for a 24 V DC relay, no special isolation for high-voltage circuits. LED indicator on the coil side gives a quick visual on pickup without needing a meter.

Frequently asked questions

Where can I buy LY4N-D2-DC24 and how do I get a price?

The LY4N-D2-DC24 is sourced and quoted to order against an RFQ through independent distribution. Submit an RFQ for current availability and pricing.

What is the closest functional second-source — MY2ZN-D2 DC24?

The MY2ZN-D2 DC24 is a DPDT relay (half the poles) with lower contact ratings — 5 A at 240 V AC vs 10 A on the LY4N-D2-DC24 — and uses an 8-pin socket. It will not drop into the same 14-pin socket without rewiring and a contact-rating check.

What is LY4N-D2-DC24's listed series?

The LY4N-D2-DC24 belongs to the Omron LY series of general-purpose relays.

What is LY4N-D2-DC24's motor rated value?

The LY4N-D2-DC24 is listed as Motor Rated: Yes, with a horsepower rating of 1/2 hp at 240 V AC.

Will LY4N-D2-DC24 drop into a panel specified around MY2ZN-D2 DC24 without rewiring?

No. The LY4N-D2-DC24 uses a 14-pin socket; the MY2ZN-D2 DC24 uses an 8-pin socket. The contact form also differs — 4PDT vs DPDT — so rewiring and a socket change are required.
