Transmitters for sensor - PLC communication

[seranko]

Hey guys,

I have a PLC with analog inputs (0-5 V, 0-10 V, +/-5 V, +/-10 V, 0-20 mA or 4-20 mA) and I would like to sense temperature, PH, ORP (Redox Potential) and Dissolved Oxygen (DO). I need some transmitters to use with the probes, do you guys know where to find some designs of them ?

thanks for your help...

transmitters...

U must to read your sensors by a micro controller & then send it to your PLC (best processor fr this work can be a AVR like mega64 )

Re: transmitters...

If you can explain the prob. in some detail, i may be of some help to you. 4-20mA is output from a transmitter that you are recieving as input. Am i right??
