OMRON RELAY LY2N-J 200/220VAC LY2NJ 200220VAC LY2N-J 2OO/22OVAC

Omron LY2N-J | LY Series DPDT Power Relay — 10A / 250V AC / 8-Pin Plug-In / LED Indicator / Arc Barrier

DPDT, LED Indicator, and an Arc Barrier That Handles 2,000V AC

The LY2N-J is the LED-equipped variant of Omron's LY2N power relay — the "J" suffix indicating a built-in operation indicator that lights when the coil is energised. This visual status confirmation is useful in panel builds where relay actuation needs to be visible without test equipment. The arc barrier provides 2,000V AC dielectric strength between the open contacts, covering switching conditions where high-voltage transients are a concern.

The DPDT (Double Pole Double Throw) contact configuration provides two independent switch sets from one relay coil. Each set includes one normally-open and one normally-closed contact, switching independently at rated load. In practical panel wiring, DPDT covers circuits that require both a making contact (to energise a load) and a breaking contact (for feedback or interlock) from the same relay — two separate single-pole relays replaced by one DPDT unit.

The 8-pin plug-in format uses the same physical footprint and terminal arrangement as Omron's MY relay series. A panel already using MY relay sockets (PYF08A) accepts LY2N-J without any wiring changes. Coil voltage must be specified when ordering — the relay body and contacts are the same across voltage variants; only the coil winding changes.

Key Specifications

LY vs MY — Power Level and Physical Size

The LY2N-J fits in PYF08A sockets that are also compatible with the Omron MY relay. The key difference is power: the LY series is Omron's higher-current general-purpose relay (10A contact rating), while the MY series typically handles lower current loads. For circuits switching 10A loads — motor starters, heaters, solenoid valves at full coil current — the LY2N-J's contact rating is the appropriate specification.

FAQ

Q1: What socket does the LY2N-J require, and is it compatible with MY relay sockets?

The LY2N-J uses the 8-pin plug-in format — compatible with PYF08A (track mount/front connecting), PYF08A-E (finger-protection type), PY08 (back connecting), and PY08QN sockets. The pin arrangement is the same as the MY relay series, so existing MY relay sockets accept the LY2N-J directly without wiring changes.

Q2: What does the "J" suffix mean on LY2N-J?

The J suffix identifies the LED operation indicator variant. When the relay coil is energised, the LED illuminates — providing visible confirmation of relay status from the front of the panel. The base LY2N without -J carries no indicator. Additional suffix options include diode suppression, push-to-test button, and bifurcated contacts for specific applications.

Q3: How is the coil voltage specified when ordering?

The coil voltage is not included in the base part number LY2N-J. Add the rated coil voltage when ordering — for example: LY2N-J DC24 for 24V DC coil, or LY2N-J AC220/240 for 220/240V AC coil. The relay body is the same across all voltage variants; the coil winding differs. Confirm the panel supply voltage before ordering.

Q4: What is the contact material on the LY2N-J?

Silver alloy contacts. For standard resistive and inductive industrial loads at 10A/250VAC, silver alloy contacts are appropriate. For switching very low-level signals (under 1A, under 24V) where contact reliability matters, consider Omron's bifurcated contact variants or relay types specifically rated for micro-load switching.

Q5: Can the LY2N-J switch both AC and DC loads on different poles simultaneously?

Yes. The two contact sets of the DPDT are electrically independent — each switches its own circuit at its own voltage. One normally-open contact can switch an AC load while the normally-closed contact of the same relay provides a DC feedback signal, provided each circuit stays within the rated limits per contact.
