I/O cables, digital
Description
Cable type
Unscreened cable
Plug type
Plug with grid dimension 5.08 mm (see Appendix A.2).
Table 3.2 Specification for I/O cables (digital)
Recommendation: Divide the connector blocks in such a way that
associated signals are present on the same plug.
I/O cables, analogue (current or voltage input/output)
I/O cables, analogue
Description
Cable type
Twisted pair cables with screen against low-frequency 50 Hz fields
Plug type
Plug with grid dimension 5.08 mm (see Appendix A.2).
Table 3.3 Specification for I/O cables (analogue)
Wiring instructions for analogue cables
-
The bus bar must be connected to the GND terminal.
-
Cables must be screened (screening connection to GND potential at both ends).
-
To achieve the best possible resistance to interference, the analogue cables should
not be laid parallel to high-interference cables (e.g. cables from converters to motors).
Recommendation: Divide the connector blocks in such a way that
associated signals are present on the same plug.
The screen is used only to screen electrical low-frequency 50 Hz fields and is not an HF
screen. The type of screen support is, therefore, not quite as important as it is for high-
speed data interfaces.
