NTC-12.03.B “Pneumatics”
Br0.00
The stand is designed for carrying out laboratory works for training specialists in automation of manufacturing processes, building automatic control systems, pneumatic automation maintenance systems. Basic elements and operating characteristics of devices are studied.
- basis-stand;
- a set of educational elements mounted on a control panel.
Structurally, the present basis-stand consists of a body with a front panel, a control panel and a tabletop of integrated working desk.
Some electrical equipment is installed inside the body:
- power source 24V;
- electronic measuring devices.
The following equipment is placed on the frontal panel:
- power switch;
- power indicator;
- programmable logic controller;
- controlling buttons and switches;
- switching jacks for assembling electric circuits;
- measuring devices;
- patch panel.
The patch panel provides the possibility of quick assembly of the required circuit, simplicity and clarity during operation.
An external power source of compressed air (compressor) is connected to the stand.
The stand is completed with a set of training elements (interchangeable devices) for assembling the different pneumatic circuits. The devices are mounted on the special brackets. The pneumatic circuits are assembled on the patch panel of the stand.
The training system is supplied with a set of methodical and technical documentation for academic staff.
