The DWYEROMEGA SSRL240DC10 is a single-pole solid-state relay engineered for AC load switching with DC control inputs. This SPST-NO relay uses SCR switching technology with zero voltage turn-on to minimize RFI in sensitive electronic environments. Rated for 10 A loads across 24 to 280 VAC, it delivers multi-million cycle life with minimal leakage current and rapid switching response. Panel-mounted with screw terminals and an LED input indicator, it integrates directly with temperature controllers for resistive heating element control.
