Hi,
I use the transmitter PT100 converter to output 4-20mA. (code: Seneca K120 RTD)
But the transmitter has no power supply. That means it must be connected to the PLC-type passive.
Please tell me how to connect the 4-20mA passive type to PLC M172. If yes, help me clear the blue area is a 4-20mA active type connection. The red area is a 4-20mA passive type, right?
Thanks,
