Multiquip LY2DUS24VDC DC24V Relay

The Multiquip LY2DUS24VDC DC24V Relay is a genuine OEM relay designed for the DCA and NGA super-silent and diesel-powered generator series, including DCA220SSVU, DCA400SSI, DCA250SSI, DCA300SSCU, DCA600SSV, DCA1100SSC, NGA150SSPUPL, and related models. As a direct OEM replacement, this relay is built to the same electrical specification as the original factory-installed component, ensuring proper control circuit operation across the generator lineup it serves. DHS Equipment stocks this part with a verified part number match so you can order with confidence and get your equipment back online without guesswork.

Key Features

• Correct 24V DC Coil Rating — Matched to the 24-volt DC control circuits used in Multiquip super-silent and diesel generator panels, ensuring proper pull-in and drop-out voltage thresholds.
• Genuine OEM Component — Sourced directly through Multiquip's OEM supply chain, identical in form and function to the relay originally installed at the factory.
• Broad Generator Series Compatibility — Fits a wide range of DCA and NGA super-silent generator models, including DCA220SSVU, DCA400SSI, DCA250SSI, DCA300SSCU, DCA600SSV, DCA1100SSC, and NGA150SSPUPL variants.
• Direct Drop-In Replacement — Designed to seat into the existing relay socket or mounting position without modification to wiring harnesses or control panel hardware.
• Protects Generator Control Circuits — A functioning relay switches control-circuit loads cleanly, preventing arcing damage to contactors and downstream electrical components caused by a failed or degraded relay.
• Electrical Safety Compliance — Using the correct OEM-rated relay in generator control panels maintains proper load switching tolerances, reducing risk of control panel faults or unintended circuit behavior.

A DC relay is an electrically operated switch that uses a low-power 24-volt DC signal to open or close a higher-current circuit within the generator's control panel. In super-silent and diesel generator sets like the DCA and NGA series, relays manage critical switching functions including start circuits, load transfer signals, and shutdown commands. When a relay fails — due to worn contacts, a burned coil, or mechanical fatigue — the generator may fail to start, fail to shut down on command, or drop key control functions entirely, making prompt replacement essential to safe and reliable operation.
