KC868-A16 analog input

[elemarek]

Is it possible to connect an analog sensor with a 4-20mA output to the KC868-A16? Some say only 0-5V and some say both. If so, how please? Thanks.

KC868-A16 board: analog input: A1,A2 for 4-20mA A3,A4 for 0-5v dc

I have four three-phase motors and I need to read one phase of each motor. I am using the KC868-a16 and the JXK-10 CTs, two with 4-20mA output and two with 0-5V output.

The CTs have two inputs for 24V +/- power supply and two +/- 4-20mA or 0-5V outputs. In this project, I joined the "Out -" outputs of the four CTs and connected them to the analog GND of the KC868-a16. The "Out +" outputs were connected to each specific 4-20mA input A1, A2 and 0-5V A3, A4.

Is this connection correct?

KC868-A16 not support CT clamp sensor. you need use M30 board for CT clamp.

I made the connections and it's working!

The CT I'm using has a 4-20mA or 0-5V output and not AC voltage.

ok, i see now, you are using DC CT sensor.
