Digital I/O board SDCS-IOB-2
Layout and jumper settings of the SDCS-IOB-2x board
There is a card holder available as option for fastening the SDCS-IOB-2 board. For more information
see chapter Dimensional drawings.
As described at the beginning of the chapter, there are
various options for configuring the inputs/outputs.
The board IOB-2x has 8 digital inputs and 8 digital
outputs.
There are three different types existing, which differ at
the input voltage level:
SDCS-IOB-21 24...48V DC
SDCS-IOB-22 115 V AC
SDCS-IOB-23 230 V AC
The inputs are filtered and galvanically isolated by
using optocouplers. Inputs can form two galvanically
separated groups by using either X7:1 or X7:2.
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.
I/O via SDCS-IOB-2x / IOB-3 and SDCS-CON-4
The cable length between X1:/X1: and X2:/X2:
is max. 1.7 m (D1...D4 converters)
is max. 4 m screened (required for D7 converters)
between X1:/X3: is max. 0.5 m because of EMC rea-
sons.
See chapter Other cables.
