SECTION 1 GENERAL INFORMATION
1.1 INTRODUCTION
The DPS is a family of digital panel indicators developed with a
variety of features for the solution of field problems.
As part of ERO ELECTRONIC background, this family also
maintains a high standard in quality, reliability and man/machine
interface simplicity, but it encompasses performance typically built
in very expensive instruments.
Features like frequency input, switching power supply, square root
extraction on the input variable, linearization by keyboard with the
setting of 9 breakpoints (10 segments), max. value data hold, min.
value data hold and analog retransmission of the displayed value
offer the widest range of possible application.
The two color custom integrated display with 4 numerical digit, 2
alphanumerical characters and 6 indicators, is an example of the
particular attention given to the design of the man/machine
interface.
The DPS comes with a complete availability of ranges from thermo-
couple, RTD and mA, digital filter, two logic inputs, two independent
alarms and it can be also supplied with serial communication interface
and a galvanically isolated auxiliary power supply.
