2.3 Connecting the DEICE-Controller

The diagram below shows the layout of the DEICE-Controller's connectors:

Power supply

The sat-nms DEICE-Controller is prepared to use two different 24VDC power supplies: 24VDC is for the controller and processor circuit. 24V_EXT is used to supply the digital inputs and outputs. The DEICE-Controller is prepared for redundant power supply. So it is possible to supply the DEICE-Controller with one, two or four power supplies. We strongly recommend using minimum 2 power supplies to ensure the maximal system stability of the DEICE-Controller. The following pictures show you how to connect the power supplies to the DEICE-Controller.

The power supply for the +24VDC circuit has to have a minimum current load of 150mA. The supply for the 24V_EXT has to have a minimum current load of 500mA plus the current that will be taken from CON14 and the peak current of the biggest digital output to be controlled. Do not exceed the current-limit, in the circuit of 24V_EXT is no fuse implemented! The maximum peak-current for switching the digital outputs is 5A.

The fuse for +24VDC circuit is directly beneath the RJ45 connector CON1. In case of damage only put in their 2A types. Otherwise the sat-nms DEICE-Controller might be damaged.
