The "PLC-BS9" has been designed to study the control and handling techniques of a pneumatic actuator through a PLC. The actuator is a double acting pneumatic cylinder that allows moving a platform. The displacement of the piston axle is detected by a linear displacement sensor LVDT. The position of the pneumatic cylinder is controlled by two proportional electronic valves. The pressure difference between the piston inlets is measured by a differential pressure sensor and the supply of compressed air is provided by a compressor. The pneumatic cylinder position is controlled by PLC depending on the obtained signals from the position sensor.
* Available PLC models of different manufacturers: PANASONIC, SIEMENS, OMRON, MITSUBISHI, ALLEN BRADLEY, etc.
