Steca TE A603+
Expansion module (Slave)
X
Description
The Steca TE A603+ expansion module facilitates modular expansion of the Steca TR 0603mc+ and Steca TH A603 M system controllers. Optional functions and system expansions allow these system controllers to be adapted individually to the system to be controlled.
The Steca TE A603+ includes six inputs for recording temperatures or pulse values as well as an additional Grundfos Direct Sensors™ input for combined temperature and flow rate measurement. Pumps and switching valves are controlled using three outputs, some of which can be speed-controlled. Up to three Steca TE A603+ expansion modules can be connected as bus slaves via the Steca TPC 1 bus to the Steca TR 0603mc+ or Steca TH A603 M system controller. The user-friendly menu of the system controller is not only used to adjust all functions and parameters of the expansion module, but also monitor while it is running. Four LEDs provide information on the operating status of the expansion module.
