DWYEROMEGA / OMEGA SSRL240DC10 Solid State Relay

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. ## Technical Specifications • Load current rating: 10 A • AC line voltage range: 24 to 280 VAC • DC control signal: 3 to 32 VDC, maximum 14 mA input • Maximum off-state leakage: 0.1 mA • On-state voltage drop: 1.6 V maximum • Surge current (1-cycle): 150 A maximum • Surge current (1-second): 30 A maximum • Turn-on time: 20 ms (AC) / 0.5 cycle (DC) • Turn-off time: 30 ms (AC) / 0.5 cycle (DC) • Input-to-output isolation: 4000 Vrms • Input/output-to-ground isolation: 2500 Vrms • Operating temperature: -20°C to 80°C • Storage temperature: -40°C to 80°C • Line frequency range: 47 to 63 Hz • Input-to-output capacitance: 8 pF maximum ## Key Features • SCR-based solid-state design with zero voltage switching • Multi-million cycle life for extended operational longevity • Minimized RFI generation due to zero voltage turn-on • LED input status indicator for visual control verification • Low input control current (14 mA maximum) • Extremely low off-state leakage (0.1 mA) • High isolation voltage ratings (4000 Vrms input-to-output) ## Typical Applications • Temperature controller integration for resistive heating elements • Industrial process control switching • Environments requiring low electromagnetic noise • Panel-mounted automation and control systems ## Compatibility & Integration Optional finned heat sinks (FHS-1, FHS-2, FHS-6) support thermal management. Load circuit protection requires fuse blocks (FB-1, FB-2, FB-3) and appropriately rated fuses such as KAX-10 for 10 A loads.
