Leomatic Systems PNC P37

P37: Analog I/O

8 inputs + 4 analogue outputs
IPC bus

  • Management of 8 analogue inputs + 4 analogue outputs.
  • Both voltage and current input signals, individually adjustable over different ranges.
  • Use of a DSP microprocessor for high acquisition speed and "intelligent" processing on board.
  • Digital filter, SW programmable, for acquisition of each input.
  • PID algorithm, configurable from SW, to control the 4 analogue outputs as a function of one input.
  • Presence of an expansion connector for installation of the additional P39 fast digital I/O module.
  • Ability to receive and run customised firmware.

Leomantic provides the P37 boards with a software library that allows you to manage all their potential and create the interface for applications. The accompanying software also includes some "demo" source files, which illustrate the use of the library in various programming languages.

Leomantic is available to produce customised versions of the acquisition and processing firmware.
