Examples of application
for the expansion module
Data recording and
visualisation of measurement data
All measured values recorded from the TA 0403 expan-
sion module(s) can also be graphically represented on the
TR 0704 system controller display. A generously dimen-
sioned data storage system allows the measured values
from the last 15 days to be displayed in the form of a
graphical curve. The running times of the pumps over the
last 15 days, or even the last 13 months, can also be gra-
phically displayed for analysis. The irradiation, output and
flow values can also be displayed over the following pe-
riods: 15 days, 13 months, the last 5 years, and a 5 year
total overview.

Steca TA 0403
The TA 0403 expansion module, with freely program-
mable functions and extra inputs / outputs, was special-
ly developed to extend the range of applications of our
TR 0704 system controller. The TA 0403 module has 4
sensor inputs and 3 outputs, some of which can be speed
controlled. TR 0704 system controller provides the con-
trol signals and supply voltage via the Steca IS bus. All
functions and control parameters of the TA 0403 can be
set using the user-friendly menu system of the system
controller. Up to four TA 0403 modules can be driven by
a single TR 0704 system controller over the IS data bus.
The operator of the solar system then has the possibility
of realising individual systems with up to 23 inputs and
16 outputs. Existing systems can be extended at any time
through the use of extra TA 0403 modules in conjunction
with a TR 0704 system controller.
