CN-0325: PLC and DCS Universal Analog Input Application Circuit Using Either 4-Pin or 6-Pin Terminal Block

CN-0325: PLC and DCS Universal Analog Input Application Circuit Using Either 4-Pin or 6-Pin Terminal Block. This circuit provides a two, 16-bit, fully isolated, universal analog input channels suitable for programmable logic controllers (PLCs) and distributed control system (DCS) modules. Both channels are software programmable and support a number of voltage, current ranges, thermocouple and RTD types. The evaluation board contains two different fully isolated universal input channels, one with a 4-pin terminal block (CH2) and one with a 6-pin terminal block (CH1)
