The brand new concept NetControl PRO+ is available! 

The PRO+ series of NetControl is distinguished by the large number of input-output circuits (total 32 pcs.: open collector outputs and alarm inputs) and the possibility of adding expanders on both sides of the controller (via side slides on the DIN rail). Thus, power circuits (e.g. 220V) are not used in the main controller, but they are moved to the expanders. All input-output circuits are on detachable screw terminals (in groups of 4). All models support "Passive PoE In" - they can be powered with (11-15)VDC through the free pairs of the UTP cable: 4/5='+', 7/8='-'. On request, it is possible to add a DC/DC converter, with which "Passive PoE In" can support 20-100VDC.
