Need for group isolation will simplify the design.
The switch and the interface can be controlled using digital isolators.

Part Number: OPA4140 Hi, I am evaluating this part for one of my project. While going through the website, it seems there is no dedicated evaluation board for this part. And I come to know following evaluation board, but it seems this EVB is not for sale…
0-10V/+/-10V signal outputs to Servo controllers, PLCs, CNCs, some customers said the frequency is 1KHz but there is no limit according to TIDA-00170, TIDA-00119. I'm checking the frequency response of servo/PLCs/CNCs. Do you know it?
Other Parts Discussed in Thread: TIDA-00119 , ADS8638 Hi,
We need to measure 8 channels 4-20mA, up to now it is easy. But we need an accuracy of 0.1%.
To convert the analog input we will use an 12bit or better ADC.
I found schematic of your TIDA-00119 board…
