Spec Sheet Description
Modular Automatic Process Controls
Suitable to study courses where the familiarization with the concepts of process, regulation and stability are required.
The different command and control blocks are electronic kind but appear as modules which input/output relation is important to be known
Using a frame for vertical mounting of the modules and the power supply unit, the different cards are assembled for conditioning, setting, regulation and display of signals that are connected to the studied process.
This kind of mounting enables to use the system also for collective explanations and demonstrations.
