I have an analog signal, 0-10V, that I need to convert to 8 digital bits. What is best way to do this in an industrial setting? Only thing I have found is a Weidmuller RS U-D8 A/D. Anything more common?

Instead of looking for such hardware (0-256 granularity!) just connect said 0-10 VDC signal to any major automation platform Analog Input point then scale the signal's Engineering Units as InputMin = EUMin = 0 and InputMax = EUMax = 256.
If this is not good enough, create a SINT (Short Integer) tag and Move/Copy the scaled values of the Analog Input point into the 8-bit SINT tag.

Given that have already found a Weidmuller unit that can do it, it's certainly not the only way, but it is a way to do it. Among the lower cost models is the Automation Direct Click, for which the software to program it is free.
+1 for the Click

CPU with analog ~ 130.00 USD
8 point output ~ 33.00 USD
Greater flexibility.

Curious..Then what?

Not the only way...A better way maybe...
I presumed that a 2017 "industrial setting" will contain at least one PLC...The analog feature could be added if not available...
Texas Instruments provides some 'Arduino Class' 8-bit Analog-to-Digital converters (http://www.ti.com/lit/ds/symlink/adc0802-n.pdf), however, this is not what I would consider suitable for a "industrial setting"...
I came across this thread because I was asked to do something similar and I was wondering how to price it. But, really, are you serious? The ADC0802 series is not "Arduino class" Those things have been running on industrial instrumentation since the early 80's!
