I am using Moore APACS/Quadlog PLC. The analog cards are Moore SAM (Standard Analog Module). The SAM accepts 4-20 mA DC two-wire transmitter signals and provides the 24 V DC loop power. The inputs need to be sinking type.
I have one input from an analyser which is 4-20 mA DC signal which does not need loop power because it derives its power from the analyser and is non-isolated. I want to connect this to the SAM module and achieve signal isolation for input to the SAM at the same time. Does anyone know of the solution, a suitable interface card (for example, from the range of Pepperl & Fuchs?).
