4-20mA analog signal loop with power supply

Hi, i want to ask if the FLX3402 is able to read 4-20mA analog signal when using the same pin for signal and power like this
If yes then does this need to set the switch to any different way or wiring?

Hello,

I would review the user manual for the FLB3204, it does mention a 4-20 signal loop.

Also, I would create a case at Mysupport.hme.se. Your local support team will be able to assist you better.

Hi Kelvin
FLB3204 is cellular modem 4G module, isnt it?
in FLX 3042 i cannot see the signal loop

Hello,

You are correct, my apologies.

It was a mistype on my end. The FLB3402 documentation has the wiring diagram for the IO expansion card.
