Workstation Process Automation with IO2USB interface and matched control and training software:

The workstation Process Automation offers a wide range of training possibilities, ranging from simple open loop control tasks to closed loop PID feedback control. It provides an optimum platform for lessons on open-/closed loop control systems. The workstation is equipped with two water tanks and various actuators/sensors and an operator panel for manual operation.

The included IO2USB interface makes all signals of the workstation accessible on the computer via the matched software. The software not only allows control of the system but also includes didactically conditioned exercises and solutions for several control situations. Tasks like open-loop and closed-loop controls can be edited. The software allows to work with the real workstation or with a simulated system.
