Specifications: The APY214E is a through-hole DIP-4 relay designed for safe and reliable switching of medium-high voltages. It manages 130mA at 400V (AC/DC) with a 20Ω on-state resistance. A key safety characteristic is its 5000Vrms isolation rating. The relay switches with 500μs turn-on and a fast 30μs turn-off. Engineered for industrial applications, it operates from -40°C to 85°C, activated by a standard 1.2-1.4VDC input.

Application Scenarios: This component is essential for interfacing with medium-high voltage lines in a serviceable format. It is used for isolating feedback signals in offline flyback converters, switching high-voltage indicator neon lamps, providing a safe interface for piezoelectric igniters, and in power monitoring equipment for sampling high-voltage lines, offering a robust and isolated switching solution.
