ICB
ICB is an interconnection board consisting of six 64-pin ICB bus slots to accommodate printed
circuit boards (PCB of Euro standard format).
LIO
The printed circuit board LIO offers the serial interface RS 232 and as an option 4 analog outluts
and an optically isolated serial interface or CAN open.
PSV/PIC Combination
*)
The PSV card (signal processing) carries out the A/D conversion and the real evaluation of
each measuring signal. This includes also all primary and all secondary variables: all
concentrations, temperatures, pressures and flow measurements. Any temperature and
pressure compensation is carried out from PSV. Linearization, zero and span calibration are
also executed in the PSV card.
The PIC card (Physics Interface Card) supplies the photometer components and the
individual sensors with the individual required operating voltages and transmits all measuring
signals to the signal processing unit PSV.
DSP (alternatively to PSV/PIC Combination)
*)
The DSP card (Digital Signal Processing) supplies the photometer components and the
individual sensors with the individual required operating voltages and carries out the A/D
conversion and the real evaluation of each measuring signal.
PCB
*) For new models the combination PIC/PSV is replaced by a single DSP board.
