I am using Simeas P P50,P55 in MCC V,I,KW,PF (4-20mA) hardwired Signals for Siemens PLC but When im connecting both AO from Siemeas P to PLC d value of analog is not stable continuously changing in Siemens HMI.

When i read manual of siemeas P then i found these "The two channels of the module are not galvanically isolated against each other".

Please anyone help me

How can i use these analogs without adding any isolator???

Very Urgent!!!
