As described at the beginning of the chapter, there are various options for configuring the inputs and outputs. The board SDCS-IOB-3 consists of the 5 analog inputs, 3 analog outputs, a galvanically isolated pulse encoder interface and a current source for tempera- ture measuring devices.

If these boards are in use, they have to be mounted outside the DCS module. They must be mounted in a way, that the conductive supports have a good con- nection to ground of the installation.

The SDCS-IOB-3 is substituting the standard AI, AO and encoder connections of the SDCS-CON-4.

The cable length between X1-X1 and X2-X2 is max. 1.7 m (D1 - D5 converters) or max. 4 m screened (required for D6 and D7 converters). Between X1-X3 it is max. 0.5 m because of EMC reasons.
