AC Transducer Bench Testing

[afm]

Hi all,

I have a AC current transducer that I want to bench test to ensure I am getting a 4-20mA output. I am using a AE001 unit. It is very simple, with only an M12 cable that I have wired the following way: L+ on 24V supply of PLC (brown wire) , L- on GND of PLC (blue wire) , and IO-Link output of PLC (black wire). I am using an X20DS4387 IO-link module. When I wire and power my PLC, I get no output when live monitoring my PLC. I am unsure how to externally bench test this as there are no terminals on this CT like other transducers I have worked with.
(Current sensor with IO-Link)

For context I previously used an ACT050-42L-F with an IFM DP2200 wired the same way to my PLC that worked well. With no load, I see an output of 4.0 mA. My goal is two eliminate these two components with this one sensor. I am new to instrumentation so all advice is appreciated. Thanks!

At the moment I do not have a lot of testing/measuring instruments on me aside from a basic MM, basic signal generator, and a variable PS for bench testing. See below:

Do you have the 4-20 ma signal on the white wire? Why not simply use that signal to the PLC (analog input). What PLC do you have?

Its a B&R X20CP0483 system. Unfortunately the only analog input module I have is for +/-10V signals (X20AI4222). I have this IO-Link module (X20DS4387) that can operate as IO-link or standard input/outputs, so I wanted to see if it would be possible to get my output while eliminating the converter. But I guess a convertor is needed if I am using this hardware?

Add a 500 ohm resistor from your analog input to common. The 4-20 ma signal will show as 0-10 volts.

Maybe 2-10 volts
