10 Appendix «Motherboard Design Guide»
10.1 Introduction
The present documentation «Motherboard Design Guide» contains helpful
information on the integration of the DEC Modules 24/2 into printed circuit
boards. Contained therein are recommendations for possibly needed 3rd par-
ty components, suggestions on layout, terminal assignment as well as circuit
samples.
Warning:
a
Development of printed circuits boards requires specific qualification
and should only be performed by experienced electronics engineers.
The present brief instruction is intended to serve as supporting aid only
and does not claim completeness. Upon request, maxon motor ag is
glad to assist and to offer customer-specific motherboard designs.
10.2 External components
10.2.1 Pin socket
The connector arrays used in the DEC Module 24/2 permits two possible
types of connections. The module can either be mounted on socket terminal
strips or soldered directly into the printed circuit board
.
Pin socket recommendations:
Specifications:
–
Pin socket vertical, single row, mates with pin header 0.63 x 0.63 mm,
pitch 2.54 mm, 2 A, contact material gold or brass
Pin socket 8 poles:

10.2.2 Supply voltage
To protect the DEC module from damage an external fuse, a TVS-diode and
a capacitor in the power supply voltage line are recommended.
