Multiquip LY2DUS12VDC Relay with Diode - OEM Replacement Part for DCA Generators

This 12V DC relay with integrated diode protects the electrical control system on Multiquip WhisperWatt DCA series generators rated through 150 kW. The relay controls critical switching functions in the generator's control panel, while the built-in diode suppresses voltage spikes during coil de-energization, preventing damage to sensitive electronic components including the voltage regulator and control module. This relay is a common failure point in generator sets experiencing electrical system malfunctions, emergency shutdown conditions, or SCR system errors as referenced in Multiquip service procedures.
