INTRODUCTION
Panelmeter AP 11 is 5 digit programmable apparatus for universal use. Apparatus is controlled with digital
signal processor with A/D transducer. Panelmeter is operated with key-board placed on front panel or with
control software that is used for setting of all parameters and archiving measured values. Panelmeter has to
be provided with communication line, variants of communication lines are in ordering code. Control soft-
ware is included in standard delivery. Panelmeter is equipped with three-colour display allowing for a quick
check of limits within measured value oscillates. Visually interesting element is auxiliary horizontal baro-
graph. Offer of input signals includes resistance temperature sensors (Pt100, Pt1000, Ni1000/6180ppm,
Ni1000/5000ppm), thermocouple (J, K, E, T, R, S, B) and unified outputs from sensors of technological pro-
cesses (4-20 mA, 0-20 mA, 0-10 V). Type of panelmeter with universal input with galvanic separation is also
available. In this case necessary type of input signal is simply configured from keyboard during installation
of panelmeter into technological equipment. Advantages of this type is higher accuracy, galvanic separa-
tion of input signal and universal use and thus minimizing number of spare pieces to ensure uninterrupted
operation. Type AP11 is produced also in modification with more inputs, particularly in following modifica-
tions: 2x Pt100; 2x current signal 0(4)-20 mA, 1x current signal 0(4)-20 mA + 1x voltage signal 0-10 V; 4x
current signal 0(4)-20 mA; 4x voltage signal; 2x current signal 0(4)-20 mA + 2x current signal 0-10 V. Power
source with load capability 100 mA, that can feed current loops of passive sensors, is built in panelmeter.
It can also be equipped with two or four limit switches whose outputs are relay switching contacts. Functi-
ons of switches on multi-input panelmeter types is programmable. E.g. any limit switch (or more switches)
can be assigned to any input. Limit switches can be compared also with value of sum or difference of two
inputs. Desired value is set individually for each limit switch or together for all limit switches when any de-
viation from common desired value can be set for each limit switch. Hysteresis and reaction of output relay
on achieving of desired value can be set on each switch individually. Limit switches can be set also for sa-
fety function. Then the switch after its connecting has to be deactivated. There is an variant with analogue
output that can be galvanic separated in panelmeter ordering code.
With multi-stage types of panelmeters analogue output can be assigned to any input by a program, even-
tually to sum or difference of two inputs. Any of the communication line variants can be used for commu-
nication of panelmeter with PC.
Communication lines RS232 or RS485 (can be galvanic separated) are in ordering code. Two communication
lines RS485 (one can be galvanic separated) or combination of two communication lines RS232 and RS485
can be used for above standard applications. Communication enables not only setting of parameters and
data archiving, but regarding the possibility of addressing of individual panelmeters it can be also used for
interconnection of bigger number of apparatuses and controlling of complete technological lines. Apparatus
features offers large possibilities of its usage, not only for simple rendering of measured signals but also as
signal transducers, galvanic separation, data collection for their processing on PC, as limit switches, simp-
le two-state regulator, apparatuses for failure signalling or as mathematical units.
