Additional Details:

The AQY210SZD01 operates by emitting light from an LED when a control signal is applied. This light activates a photodiode array that, in turn, drives a MOSFET. The MOSFET then switches the load circuit. The optical isolation ensures no electrical connection between the control and load circuits, providing excellent isolation and safety. This SSR is known for its robustness and reliability, making it suitable for a wide range of applications requiring isolated switching.
