3.5 Controller
Information on controlling via bus systems can be found in
the manuals for the relevant field bus variant of the SFC−DC−...
(in preparation).
In the case of control via digital I/Os (type SFC−DC−...−IO) note
the instructions on connecting and on the function of the I/O
interface in chapter 6.
3.5.1 I/O controller (only type SFC−DC−...−IO)
The controller connection of the SFC−DC−...−IO with I/O inter
face is used for communication with the higher−level con
troller via digital I/Os.
Caution
Long I/O signal cables reduce the immunity to interfer
ence. Make sure, therefore, that the maximum permitted
I/O signal cable length of 30 m is not exceeded.
Warning
If a 24 V DC voltage is applied and the output pins are
used incorrectly, the device may be seriously damaged,
therefore:
·
do not connect voltage to the outputs.
·
note the current limitation at the outputs
(see section 5.6.3).
Information on controlling the SFC−DC via the I/O interface
can be found in section 5.6.
Recommendation:
Use the control cable type KES−MC−1−SUB−15−.... You will then
comply with protection class IP54.
