Hi all,

I have a combined PH and CF transmitter of which can be found here

I need to make 2 x 4 - 20mA loop isolators that I can connect to each output. The unit runs on a 24V power supply

Someone has pointed me to some of the components

This will be the fist time I have made something like this and would like to do it on small prototype boards with chip housings etc.

Can anyone provide me with the correct parts from farnell or RS and possibly an easy to understand diagram?

I have used this device before but they are very expensive at £134.40 inc VAT
