ZL-7817A PID Controller
ZL-7817A is a PID controller. The control result will be more accurate compared with on/off control.
With an auxiliary output for timer on/off, it could control a load such as fan.
The auxiliary output can also work as high temperature protection. When the temperature is higher than a set point, it will be energized. If drive a fan, it means exhaust hot air out immediately.
The output R1 is not a relay, but a TRIAC (a kind of semiconductor). The benefit is it can drive inductive and/or capacitive load to 7A current.
