Co Trust CTS7 231 7PC32 RTD Measuring Module,2AI×RTD,16Bit precision,Isolation/4AI×RTD,16Bit precision,Isolation.It also allows the CTS7-200 PLC to measure three different resistance ranges. You must use DIP switches to select RTD type, wiring configuration, temperature scale, and burnout direction. Both RTDs connect to a module must be of the same type.
