The Lab-Volt PLC Applications, Series 8075, aim to further develop the students’ understanding of PLC programming that was acquired either with Lab-Volt’s Programmable Logic Controller Training System (Model 3240) or other equipment. Basic principles are integrated with more advanced concepts in order to design small-scale systems typical of what can be found in industry. Through practical examples, students will gain a strong knowledge of PLCs and of the studied applications. The systems’ training capabilities are enhanced by their modularity and by the ability to use instructor-inserted faults. Fault switches are included on selected modules to enhance troubleshooting activities by simulating open coils and contacts, defective contacts, shorted connections, and crossed wires. The modules of the PLC Applications Series can be interconnected with those of other Lab-Volt training systems for interdisciplinary training applications. Connections are made using flexible, PVC-insulated connecting leads terminated with 2-mm plugs. The control circuits operate at 24 V – DC and are compatible with a variety of PLCs. The PLC Applications series is divided into seven systems, each system covering a specific topic related to PLC controls. The Traffic Light System, Model 8075-10, is a well known classic PLC training system pertaining to vehicle and pedestrian traffic control at an intersection. The Electro-Pneumatic System, Model 8075-20, uses a PLC to control a variety of pneumatic industrial applications. The Electro-Mechanical System Using DC Motor, Model 8075-30, and the Electro-Mechanical System Using Stepper Motor, Model 8075-40, enable diverse PLC-controlled positioning and motion processes.
