I am using UM330 in the factory. I think I can get sensor values from INA219 by using pins 16 and 17, but I don't know how to connect them. I already burned one Arduino.
If you are not using 15V DC loop power, it looks like pins 16 and 17 are 4-20mA output, so you would need a 4-20mA receiver.
I'm not familiar with your device, but generally you read 4-20mA output by placing 250ohm resistor between the pins. That gives 1-5V output.
Read you manual and verify with multimeter.
Safer option is to use ready made converter module.

Do you know which loop power supply is being used?
I'm trying to use ina219, should I lower vcc 5v?
Power comes from outside on pins 8, 9, and 10.
That is the main power.
Which loop power supply is being used 15VDC or 24V
As a result of measurement, the power voltage was confirmed at 16 and 17.
I prefer a 51 Ohm resistor, and reading with 1.1volt Aref.
That makes the result independent on supply fluctuations.
Default Aref is for ratiometric measurements, not for absolute/voltage measurements.
The INA219 has a too low resolution (1.5625mA per A/D step) to read 4-20mA sensors, unless you change the 0.1 Ohm shunt to 100 Ohm.
Leo..
What was the voltage?
