Common Mechanical Dimensions for COM-C Modules
After mounting the COM-CA Module parallel at a basis board the rotary switches, LEDs and the
fieldbus connector are on the top side and are angled to the basis board. The edge of all front ele-
ments are in one layer which is 2.5 mm ahead of the edge of printed circuit board of the COM
Module.
The COM-CN Module has to be used if the mechanical dimensions or order of the LEDs, switches
and fieldbus connector doesn't fit. In that case you have to place these components directly on the
motherboard and feed the signals to the connector X2 of the COM-CN Module.
Note
Please take care on the isolation distance, because the optical isolation interface is on
the Module!
Especially for 12 MBit PROFIBUS the distance should as be less as possible.
For Ethernet, the signal traces should run parallel and should have the same length.
Please refer at the fieldbus standards for further information!
