Thank you brewer, it may be useful.

No, it's Non-Loop Powered transmitter

Joe E, I had try the wire as short, but there is no change. And your attached manual is helpful thank you.

we are using RSLogix 5000 v19.01.00 software. And i couldn't understand your question in the above comment which are "Are the alarms disabled? If the alarms are enabled that could limit your channel".

  I have a problem for getting the 4-20mA input via 1769-IF8 I/O module. My field device is in good condition, but my AI card doesn’t respond. When I have been browsing about it, most of them said, the impedance of the field device and AI module are not matched. I don’t have any idea about how to match the impedance of both,explain to me how should match the impedance successfully?

Hi,  We are working with AB-CompactLogix L32E controller including Compact I/O 1769-IF8 analog input module. We have been configure 1769-IF8 module as engineering units (Min 4000 to Max 20000). At the analog input side we have connected Non-Loop powered 4-20mA Amplifier as per 1769-IF8 wiring drawing (Iout+ to Iin+ and Iout- to V/I in-). The amplifier successfully generate the 4-20mA signal without oscillation at the output terminal. But the controller shows only 3200 (engineering unit) value with no change.   We don't know what's the problem is. Also we had double check our input wiring connection and module configuration there is nothing wrong. Apart from that please give us solution to eradicate this problem and give any suggestion.
