Cr310 connecting 4 wire pt100 and 4-20 mA (using internal shunt)


andreadale Oct 14, 2020 03:58 AM

hello,  on my cr310 i have to connect a 4 wire pt 100 to read a temperature and 4-20 mA (using internal shunt) to read pressure.

If i try with shortcut to add in generic measurements to add 4-20 mA input (using internal shunt) the program said that cannot be added because there are not enoug free 4-20  mA connections.

The 4wpb100 are using the 1H and 1L.

I tryed to change wired connection on pt 100 and leave 1H and 1L free for 4.20mA but i think i cant do that.

There is an easy way to solve my problem ?

Thanks

Andrea

Try removing the PT100 measurement, adding the 4-20mA, then add back in the PT100.
