ATR244, 2AI, 2AO, input , output isolation
Posted: 07/10/2020, 8:04
Good morning,
We , at University Oradea, have an ATR244 with supply voltage 24V AC/DC, with 2 AI and 2 AO.
I want to use it for measuring 2 temperatures with thermocouples of type K, via the 2 analog inputs, and then transmit the temperature values via the analog outputs (0...10V) to a Data Aquisition System.
One measuring point (K thermocouple) is at the GND potential( PE, protective earth), but with the second thermocouple i want to measure the temperature of a conductor which carries an AC current, so the thermocouple has a live , floating, potential (the AC voltage of that conductor)
Are the 2 AI ISOLATED from each other or not?
Are the 2 AI ISOLATED from the power supply (24VAC/DC) other or not?
Are the 2 AO ISOLATED from each other or not?
Are the 2 AO ISOLATED from the 2 AI or not ?
And finally can make these measurements how i intended or not?
Thank you for your time,
Best regards
Remus
