SIMATIC 545/555/575 System Manual
Installing Series 505 Remote I/O Cables (continued)
Three commercially available cables provide an acceptable level of I/O
communication in an industrial environment.
Beldenr cable 9860 is a large conductor cable that provides a low
attenuation and distortion for long trunk lines.
Belden cable 9271 is a smaller and more flexible cable suitable for short
trunk lines and all drop line cables.
Belden cable 9182 provides an intermediate level of size, flexibility, and
useful length. The 9182 cable is also available in a version (89182)
rated for a higher level of fire resistance and low smoke-producing
properties.
The following restrictions apply to Belden cable:
Belden cable types 9860 and 9271 can be mixed on the trunk line, but
cable type 9182 must be used alone.
If the trunk line is Belden cable type 9860 or 9271, the drop line can be
Belden cable type 9271 or 9182. If the trunk line is Belden cable type
9182, the drop line must be Belden cable type 9182.
