Hello, I hope this message finds you well. 

I have a flow meter type 8030 and transmitter SE30 from Bükert. I want to connect it to Analog input module AI 8xI 2-/4-wire BA(White base unit) . I tried different ways but didn't get any results. Can someone help me, with how I need to wire the 3-wire connection to this analog input module? I choose also 4-wire transducer in TIA portal but I don't know if it should be 4-20mA or 0-20mA or +-20mA. I couldn't find anything in the manual. Attached you'll find wiring diagram of flow meter and analog module. 

Thank you in advance. 

Hello,

Thank you very much. You are right. I connected it (PNP) using HSC directly to 1215 DC/DC/DC and it worked fine. I got the frequency from high-speed counter and the K-factor for my flowmeter was 440. I did the math (f/K) and I got to the result. Now my question is: Is it also possible to connect it to DQ 8x24VDC 0.5A ST? If yes how to calculate the frequency here since there is no HSC available for this module?

if I could ask for reason of that pulse to Q copy to outside of PLC. In case you need use that output precisely as same as that HSC, you need again similar HW signal configured, with enough Hz. Your analog output-input at external system can be used only as information because of loose precise of calculation on other side, really all dpends what you have there and what you need to do. In case you want share pulses actual value you can also do comm link via suitable interface (PN/PB/Serial MB RTU,...) and share exact data with external partner. In this case freq or pulses will be at same value as actual without to loose some data and precision. This is also important, as addition to danw good sugestion about analog output signal process.

Thank you very much. I meant DI. It was a typo. 

I got it. thanks for the time.
