Specifications: The APH1223E is a high-voltage AC-output PhotoMOS SSR in a DIP-7 through-hole package. It is a 1 Form A (SPST-NO) relay capable of switching 600mA at up to 600V AC. It provides 5000Vrms of isolation and features a fast 100μs turn-on time. It operates from -30°C to 85℃ and is controlled by a precise 1.21-1.3VDC input. (Note: On-state resistance and turn-off time are not specified in the provided data). Application Scenarios: A versatile relay for medium-power AC switching. Common uses include industrial control of actuators and small motors, HVAC system fan and pump controls, lighting ballast control, power supply inrush current limiting circuits, and as a reliable interface for microcontroller-based systems to switch AC mains power in appliances, vending machines, and industrial controllers.
