EM extension module
Sensor and relay extension module with 5 outputs and 6 inputs
Article-no: 145 440 80 | Price bracket A

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
Kommunikationsmodul 1,5 mA
Smart Display SDFK 25 mA
Smart Display SD3 17,5 mA
GA3 Large Display 1 mA
AM1 alarm module 16,5 mA
HKM3 1 mA
STA-W 12 mA
WMZ 35 mA
WMZ G1 35 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 provides 5 additional relays and 6 additional sensor inputs for the DeltaSol® MX controller. Up to 5 Extension Modules can be connected to the MX via the VBus®, so that a total of up to 39 outputs and 45 inputs can be made available for the control logic. The Extension Modules themselves do not require any adjustments, they are simply connected and assigned to the controller. The inputs and outputs of the registered modules will then be available for all functions of the controller. 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.
