Changes the shape of these digital vacuum switches with respect to those previously described, from cylindrical to parallelepiped. However, the container in which they are enclosed remains in ABS and is also especially compact and extremely light to allow for its installation on board automatisms and near use.
These carefully calibrated devices are able to provide very accurate measurement values. The detected values are shown on the display, making it unnecessary to use a vacuum gauge.
The panel includes two LED indicators, one green and one red, which indicate the switching status of the two digital output signals. The switching outputs are completely independent. The switching points within the scale values, including hysteresis from 0 to 100% of the set value, are easily programmable via the buttons located on the control panel.
Other additional values can be programmed, such as comparisons between values, NO and NC contacts, the choice of the units of measure, the blocking of functions and programmed values, etc.
The vacuum connection can be made by means of a G 1/8” male or M5 female double threading connection. Electrical connection for art. 12 30 10 is pushin with a M8-4 pin threaded jack. A connection cable can be provided in PUR upon request with corresponding axial or radial connector. Instead, art. 12 30 10 A already has an integrated PUR, 2-metre long connection cable. The adjustment range of vacuum switch 12 30 10 is from 0 to -1 bar, with two digital PNP outputs that can be set by means of Teach-in. The adjustment range of art. 12 30 10 A, while it is also between 0 and -1 bar, can instead be interfaced with external logics via a 1 to 5 volt analogue output and two digital PNP outputs.
This series of digital vacuum switches is suitable for measuring and control of dry air and non-corrosive gases. These are recommended in all cases where maximum and minimum value signalling is required, set for safety reasons, in order to start a work cycle, to control suction cup gripping, and so on. In addition, with the hysteresis function, it is possible to manage the compressed air supply to the vacuum generators, allowing for considerable energy savings.
These devices are enclosed within a robust ABS container. They are carefully calibrated and at compensated temperature, ensuring high-precision measurement values.
Detected values are viewed on the main two-colour (red and green) display and programmable by the user to set different conditions. Setting values are easily viewable on a secondary display within the command panel. Two luminous indicators pertaining to outlets 1 and 2 indicate the switching status of both digital and the analogue output signals. The switching outputs are completely independent.
The switching points within the scale values, including hysteresis, are easily programmable via the buttons located on the control panel. Additional functions are also programmable, such as comparison between two values, NO and NC contacts, choice of measurement unit, programmed value and function blocking, etc.
The connection to the vacuum may be established by means of a male G 1/8” or female M5 double threading connection.
It is possible to establish an electric connection by means of a removable, rapid installation data cable, supplied as standard.
