Specifications: The APY210S is a reliable medium-voltage switching relay in a space-saving SOP-4 form factor. It is characterized by a 100mA current rating and a 400V voltage withstand capability (AC/DC), coupled with a 20Ω typical on-resistance. The device ensures operational safety with 2500Vrms of input-to-output isolation. Its switching behavior is defined by a 230μs turn-on and a 50μs turn-off period. Designed for enduring performance, it functions from -40°C to 85°C, responding to a standard 1.2-1.4VDC control voltage.

Application Scenarios: This relay is a workhorse for powering and isolating auxiliary circuits. It finds extensive use in switching small contactor coils in motor control centers, enabling/disabling auxiliary power rails in switch-mode power supplies, and providing isolated control for status indicators and alarms in industrial control panels and commercial HVAC systems.
