Ok I got the fact that the 0 volts on my analog inputs are floating so I need some signal converters to sort out the signals now if I want to put on a mixture of 4-20mA and 0-10V inputs is that going to be ok.
Bit of a dodgy drawing I know but its the best I can do at work.
+24V-----------------------------|
| |
| |
= 0.22 Cap |

4-20mA +-------> |Multiplexer
| |
| |
= 0.22 Cap |
| |
0V------------------------------|
+10V-----------------------------|
| |
| |
= 0.22 Cap |
| |
0-10V +-------> |Multiplexer
| |
| |
= 0.22 Cap |
| |
0V------------------------------|
