The FS24D10 is a miniature solid-state relay designed for medium-power AC load switching with DC control. It features zero-cross turn-on switching with a 12 Vac zero-cross window to minimize EMI, optical isolation for control protection, and a triac output stage capable of handling 10A resistive loads at 280 Vac. The relay operates with a control voltage range of 4–30 Vdc and input current range of 3–30 mAdc, with a maximum on-state voltage drop of 1.3V and turn-on time of 8.3 ms at 60 Hz. Its compact package design with integrated thermal performance makes it ideal for heating control, motor control, light dimmers, uninterruptible power supplies, and industrial process control applications where space is limited and reliable medium-power switching is required.
