Steca TA 0403
The TA 0403 expansion module, with freely programmable
functions and extra inputs / outputs, was specially developed
to extend the range of applications of ourTR 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 control 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.
Features
· 4 temperature / pulse recording inputs and
3 outputs, some of which can be speed
