It used to be EN50178. Not sure if that got rolled into a part 2 of 60947 or
separate Standard.

Hello Doug,
I’ll tackle the North American side of this discussion. I believe UL 508C
http://ulstandardsinfonet.ul.com/scopes/scopes.asp?fn=0508C.html is the
standard for the United States. Its scope states “These requirements cover
open or enclosed equipment that supplies power to control
Doug,
For the motor drives, take a look at the EN 61800 series of standards.
I'd also be wary of using EN 60950-1, at least on its own, for the processors.
If safety is involved (which it is if there are emergency stops involved) then
you have a significantly bigger can of worms on your
Does anyone know the status of this IEEE Standards development project
(P299.1)? It was set to expire in Dec 2010 and I am trying to find a resource
as to its voting status and likelihood of passing.
Thanks,
Doug

All,
I am consulting with a client that builds automation equipment used with chain
and wire rope hoists. The system is comprised of a group of modules that can
be connected via ethernet with a control console, auxilliary modules and hoist

David,
Yes, if you are calibrating as a 50 ohm system.
I believe it is actually preferred to add the 150-50 ohm adapters and calibrate
as a 150 ohm system, though. Check out the diagram at the top of the last page
of this document:
Hello David,
You are correct for the BCI clamp.
And if calibrating a CDN for 10V then it would be 140dBuV (Uo) – 15.6dB =
124.4dBuV (Umr) on the spectrum analyser.
But for either of these calibrations, do use an watty attenuator also (because
you don’t want to overload the spectrum
