Universal microprocessor regulator LB-600 was made with taking into account all of the requirements placed on the similar devices used in industrial automation. The following features compose its operational use:

A detailed description of the regulator LB-600 characteristics was introduced in a separate description and in an additional help function (file to be downloaded).

The Automation and Robotics Institute of the Warsaw Polytechnics organizes a cyclical course for the engineers and the measurements service workers and automatics with secondary technical education who should get aquatinted with operational service, programming and project usage of the microprocessor regulators series LB-600.


The regulator LB-600 is a universal, programmable, digital regulator designed for the measurement systems, control and regulator of different technological processes. The regulator can realise the following functions:
