Main features

The working voltage is 4.0 V ~ 5.5 V (DC).

External oscillation resistor and capacitor.

There is an external cadmium sulfide (CDS) sensor to suppress the output during the day.

Output can drive relay or thyristor.

Built-in two-stage operational amplifier with adjustable gain.

The control time is adjustable.

Built-in regulated output 3.1 V, directly drives PIR.

Integrated zero-crossing detection and AC power synchronous triggering to reduce power supply pollution.

z DIP16 or SOP16 package.
