1 EQUIPMENT DESCRIPTION
VPO10 is a Profibus-PA converter for discrete and analog output. It has three output channels, where
user can configure current output (4-20 mA) or discrete output with open collector (maximum current 400
mA, 24 Vdc).
VPO10 is a converter that provides connection of end elements such as control valve positioners
and other final control elements to Profibus-PA systems. The converter generates, in proportion to the
Profibus-PA network setpoint signals, 4-20 mA outputs, through analog output function blocks (AO block),
or allows actuations in open collector loads.
It is powered by a 9 to 32 Vdc voltage source and uses Profibus-PA communication protocol for
configuration, calibration, monitoring and diagnostics. Through a Profibus-PA configurator, Android platform
or tools based on EDDl or FDT/DTM it is possible to configure the measurement scales, the work units,
calibrate the instrument, monitor the measurement variables and check the equipment status. Another way
to configure the VPO10 is by locally adjustment using a magnetic tool.
VPO10 installation can be done in the field through a bracket connected to a 2 "tube with U-clamp,
it can also be installed in a wall or panel.
Prioritizing high performance and ruggedness, this converter is designed with the latest electronics
and materials technologies, ensuring long-term reliability for systems of any scale.
