RT 350

Trainer for Industrial Controllers

Technical Description

This trainer familiarises students with the operation and function of a state-of-the-art industrial process controller. The controller has freely accessible inputs and outputs. Defined input levels and step signals can be produced with a signal generator. A digital voltmeter is used to measure the input and output signals. A simple first order lag is simulated to allow the response and stability of a closed control loop to be investigated. All signals are accessible via lab jacks so a standard x/y plotter or line recorder can be used. It is also possible to control external system models with this controller. As well as manual configuration and parameter setting with keys, the controller can be configured (configuration software supplied) from a PC over an RS232 interface.
Clearly structured instructional material sets out the fundamentals and provides a step-by-step guide through the exercises.
