Implementación de un Equipo de Laboratorio de Control Industrial con Relés Inteligentes para el Control Automatizado de Motores Eléctricos de Corriente Alterna Monofásicos

Abstract

A Lab Module has been implemented for Electric One Phased Motors using Intelligent Relays (LOGO) for the Control Lab of the Mechanical Faculty, ESPOCH. Thus the students of the electric areas will carry out lab practices with technologically updated tools. The Programmable Logic Module brain is the LOGO SIEMENS 230 RC. It is a small automaton used in moderate automation works. LOGO is easily programmed through the LOGO SOFT COMFORT installed in a computer. This software has two programming editors, with tools of easy understanding; the KOP (contact scheme) use contacts similar to those of the electrical circuit design for the cabled logic; the FUP (function diagram) uses logical gates like the electric circuit design. The user will choose the editor which meets needs and knowledge. The designed program passes to the logo through transference cable (PC ↔ LOGO). It should be added that the LOGO, the software version and the transference cable must be compatible to avoid communication problems with the computer. Once the module is finished and the lab tests carried out, it is concluded that it is possible to program any automatics system supporting the LOGO capacity, 8 inputs (pulsars, run ends, etc.) and 4 outputs (contactors, motors, etc.), having the alternative of using enlargement modules of the LOGO if the requirement is major. Finally, it is considered that the LOGO SIEMENS is very useful for didactical purposes, the students could train himself progressively from very simple applications such as lighting a lamp up the complex systems including wait times, temperature variations, level, among other applications.
