Analog Isolator

Which country are you seeking this in? All the following are readily
availabel next day in the UK from the likes of Farnell and RS, so probably
in major countries world-wide on a similar basis...

Suggestions:

Start with

http://www.weidmuller.com/downloads/pdfs/literature/5650140000_Electronics_CAT4_D.pdf


===

Weidmuller DK6/ISO/V-V, part No. 980683

but no spec on bandwidth, 20-28V DC power supply.

===

Weidmuller MAS DC/DC select 8594810000

100Hz bandwdith, but still 24V DC nominal PSU

===

Weidmuller WAS4 VVC DC 0-10/0-10V 8447130000

13 to 17Hz bandwidth, also 24V DC nominal but seems to be a true isolator
with a separate PSU on each side.

===

Weidmuller WAS5 VVC HF 0-10/0-10V 8447370000

20kHz bandwidth (so it will do audio!), but again 3 port isolation on 24V DC
supply.

===

But this is my personal favorite:

Weidmuller WAS4 PRO DC/DC 1 8560740000

Put one of these in your toolbox - it does more or less any type of process
signal to any other with selectable bandwidth. I've even used this as a
valve drive in a hydraulic servo system. 24V DC again though...

===

Action Instruments - now part of Eurotherm have very similar products - who
re-badged who?

===

Status Instruments SEM1100 is mains AC powered, but no clues on bandwidth.

===

Phoenix Contact MINI MCR-SL-U-U

Supposedly 100Hz bandwidth but also gives a step response of 10% to 90% of
2ms. 24V DC nominal again

===

Broderson PXU20 series

Has 115V AC and 230V AC supply options. Bandwidth given as an "upper
critical frequency" of 30Hz.

===

Siemens Simrel 3RS170 or 3RS1705

30Hz bandwidth and universal ac psu (24-240V ac) available - but not usually
stocked.

===

There are lots of others, but I haven't used them personally.

Dave, thank you for your reply.

The isolator is for use in the United States.  You have supplied a lot
of good leads. Weidmuller and Eurotherm will be my starting point.
