Analog Isolator

Any suggestions for an analog isolator? Requirements are 0 to 10 VDC in, 0 to 10 VDC out, 1% of full scale accuracy,output ripple less
0.25% of full scale, minimum frequency response - 0 t0 10Hz, input impedance greater than 10,000 ohms, load on output is 1 megohm, DIN rail mounting, prefer AC powered unit but DC powered unit is acceptable and quantity one.
Howard.

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.
