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.
