Hi,
I'm using TIOS101.
According to datasheet, Current can be limited by adjusting Rset.
And this seems to be possible regardless of PNP and NPN.
But in my opinion PNP is true, but not NPN.
Because PNP is current source, so current flow is Driver to PLC.
But NPN is current sink, so current flow is PLC to Driver.
So I think the following expression is correct.
When the driver is NPN, the limit for current input is 200mA.
(If my definition is correct, TIOS101 means that current can be limited for input / output current. Is it true?)
It's still very confusing, but I'd like to ask for clarification.
Thank you.
