SYSTEM DESCRIPTION
2.1 System Overview
The
COMBILOG 1020 is a datalogger with compact design,
combined with integrated LC-display and memory slot suitable for
PCMCIA memory cards.
This datalogger was developed for meteorological, hydrological
and environmental measuring systems, but it is equally suitable
for countless further applications in industrial production.
The
COMBILOG 1020 features high performance, compact de-
sign (SMD components), low power consumption and moderate
price.
The datalogger is equipped with 8 analog and 6 digital measur-
ing channels; further channels for numeric calculation may be
configurated. Two serial interfaces, RS232 and RS485, are built-
in, featuring communication via ASCII, PROFIBUS or MODBUS.
Data storage is achieved by internal RAM or PCMCIA memory
card, optionally.
„SELECT“ switch and 2-line LCD on the front panel allow to enter
or modify a number of different modes and functions, such as
scan rate and averaging time, as well as offset or gain.
The COMBILOG 1020 can easily be mounted on a 35 mm stan-
dard rail, using its „snap-in“ clamp, and is therefore suitable for
control cabinet installation, or similar.
Thanks to its low power consumption, battery supplied systems
are possible, whereby the use of a solar panel enables any ex-
tension of measuring period. Especially for battery supplied sys-
tems the datalogger can be delivered with reduced internal proc-
essor clock. Please note, that in this case the performance may
be reduced too.
