EM extension module
The EM extension module provides 5 additional
relays and 6 additional sensor inputs for the RESOL
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.
