Specifications: The APY212G2E is a high-current DIP-4 relay with a controlled turn-on characteristic. Rated for 2A at 60V (AC/DC), it has a 69mΩ on-state resistance and high 5000Vrms isolation. A notable feature is its 2.7ms turn-on time, which is intentionally slow to limit inrush current, paired with a 50μs turn-off. It operates from -40°C to 85°C with a wider 1.32-1.6VDC control input range.

Application Scenarios: The soft-start capability is key for protecting capacitive loads and limiting intrush. This relay is ideal for powering up large microprocessor boards, controlling the filament supply in vacuum tube audio equipment, sequencing power in multi-rail systems, and as a main switch in laboratory power supplies, where a gradual voltage rise prevents nuisance tripping and extends component life.
