<p>PURPOSE: A temperature and humidity control system for a thermo-hygrostat is provided to enable a user to easily select the activation of a DO output terminal without changing physical wire by including an activation selecting unit of the DO(Digital Output) output terminal. CONSTITUTION: The main control unit computes and outputs control output value based on present value and set value inputted from a touch screen. The main control unit(110) controls run, stop, error, and hold based on DI(digital Input) signals. The main control unit DO signal for controlling external devices based on the DO output control signals. A remote input-output board(120) inputs and outputs DO signals and transmits DI signals to the main control unit. A touch screen(130) displays present value and control output value. The touch screen displays the operation state of the DI input terminals formed in the remote input-output board.</p> |
