AO810 No output
Im using an AO810 together with TU810 connected to 8 I/P Converter, it works for several days and now the module does not give any output signal.
I test the terminal of the tu810 and it reads 0mA. What is the possible problem??
I measure the resistance of the terminal of I/P converter and its 10Kohms, is this the culprit?
how can i solve that problem?
That is the 2nd time happen i thought it was just a factory defect on our TU810 on the first time.
my connection is;
C1 --> + of I/P
A1 --> - of I/P
C2 --> + of I/P
A2 --> - of I/P
and so on..
The resistance of 10 kOhms in output circuit, if true, is too high value. As per AO810 data sheet, it should be max 500 ohms.
In order to test your AO, connect directly mA meter directly to C1 and A1, without external circuits, and force some value to AO channel.
The meter should have resistance below 500 ohms, so it will measure your output current.
The AO810 card needs 24VDC supply at L+/L- terminals, resp. L2+, L2-.
