Training laboratory bench NTC-09.14 “Automation on the basis of programmable relay” is designed to study the programmable relay and the options for its industrial applications in the construction of automated control systems. A model of reservoir is used as the controlled object.
The bench is divided into two areas:
1. Logic module “LOGO!” This area includes a programmable relay Siemens, a display unit of programmable relay inputs and outputs and a controller unit of digital and analog inputs.
2. Model of reservoir. This area indicates the controlled object and controllers. The reservoir state change is indicated by the display. The object control is possible both in automatic and manual modes.
To enable the study of the programmable relay, the bench contains four independent digital signal sources and an analog one; the signals are fed to the respective inputs of the programmable relay.
Relay programming is carried out using a PC.
