VBus
The number of VBus® accessories that can be connected to one controller depends on the sum of their current consumption and on the current supply of the controller VBus®.
Device Maximum current consumption
VBus®/PWM interface adapter 6,5 mA
VBus®/USB interface adapter 6,5 mA
VBus®/LAN interface adapter 6,5 mA
Datalogger DL2 1,5 mA
Datalogger DL3 VBus® 1-5: 10 mA
VBus® 6: 0.5 mA
KM1 Communication module 1,5 mA
Smart Display SDFK 25 mA
Smart Display SD3 17,5 mA

The VBus®-Repeater amplifies the VBus® signal of a controller and supplies a current of 200 mA in total to modules connected.






The EM extension module can be connected to the DeltaSol® MX, DeltaSol® BX Plus or to the DeltaTherm® HC and provides 5 additional relay outputs and 6 additional sensor inputs. The EM can be used for all optional functions of the above mentioned controllers and can also control a heating circuit. With 5 extension modules and its 2 internal heating circuits, for example, the DeltaSol® MX can manage no less than 7 heating circuits complete with individual room thermostats.
