quick overview :
Inside a laboratory for automation technologies, the trainer is the necessary tool for the training of technicians operating industry, for installations maintenance and program designing levels. Totally carried out with industrial components, the trainer enables the development of a solid experimentation and a high content of knowledge on PLC programming and the solution of more complex problems related to automation, with particular reference to process control with HMI/SCADA software and to communication in
industrial networks. The PLC installed in the trainer is one of the most powerful and used in industry. It provides many digital inputs and outputs accessible by means of terminals Ø = 4 mm and Ø = 2 mm present on the front panel. The digital outputs are available as relay outputs or transistor outputs for all those applications which need quicker timing. The logic state of the digital inputs and outputs is displayed via LED diodes on the PLC. The analog signals processing allows it to be used within the industrial regulations in closed-loop PID controls.
