Steca TA 0403

The Steca TA 0403 expansion module, with freely programmable functions and extra inputs/outputs, was specially developed to extend the range of applications of our Steca TR 0704 system controller.

The Steca TA 0403 module has four sensor inputs and three outputs. Steca TR 0704 system controller provides the control signals and power supply via the Steca IS bus. All functions and control parameters of the Steca TA 0403 can be set with the user-friendly menu of the system controller. Up to four Steca TA 0403 modules can be operated by a single Steca TR 0704 system controller via the IS data bus. The operator of the solar energy 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 Steca TA 0403 modules in conjunction with a Steca TR 0704 system controller.
