Tom@Pton (Customer) asked a question.
GS20, CLICK & EA9 on a LAN network.
I am using AI2, 4-20ma for control of the GS-20 in a pumping application. It works fine. No issues.
0-100 PSI.
I would like to monitor another pressure via its AI1, 0-10 volt and read that via the CLICK. No interaction with the existing loop. 0-15 PSI
Is this doable? What parameters?
You could read P03.47 (Modbus register 400816)
This parameter holds the AI1% value that gives you the percentage of 0-10V at AI1.
The value is given as 0.00%-100.00% with 2 implied decimal places.
EX.
10000 = 100.00% (10V)
5000 = 50.00% (5V)
You should set the following parameters
P03.00 = 0 (No function)
P03.28 = 0 (0-10V)
Leave P03.63-P03.68 all at their default values.

Scaling to PSI can be done in the Click with a Math instruction.
(AI1% / 10000) * 15.0
