規格與應用場景
Specifications: The OPT1412EH is a Normally Closed (NC) relay offering high isolation in a compact SMD-4 form. It is rated for 500mA at 60V (AC/DC) with a 1Ω on-state resistance and a significant 5000Vrms isolation rating. In its NC configuration, it opens in 500μs and closes in 250μs upon control signal application. It operates from -40°C to 85°C with a 1.2-1.5VDC input.
Application Scenarios: This fail-safe relay is crucial for safety and protection circuits requiring a default-closed state. It is implemented in redundant power supply OR-ing circuits, safety door interlocks on industrial machinery, emergency lighting test switches, and watchdog timer outputs that must force a system reset by opening a critical power path, ensuring functional safety in critical systems.
