Specifications: The APW614EH is the SMD-8 version of a high-voltage combination relay (NO+NC). Each channel is rated for 120mA at 400V (AC/DC) with 20Ω on-resistance and 5000Vrms isolation. Switching times differ between NO and NC channels. It operates from -40°C to 85°C with 1.2-1.5VDC. Application Scenarios: Provides a compact, high-isolation changeover function for medium-high voltage signals. Used in advanced instrumentation for input range or attenuation switching, high-voltage power supply output selection, and safety interlock systems that require switching between two high-voltage paths.
