 This schematics shows the first stage of the input circuit of one Analog Input channel.\\ This schematics shows the first stage of the input circuit of one Analog Input channel.\\
 The input is optimized for low or mid impedance voltage signal sources. \\ The input is optimized for low or mid impedance voltage signal sources. \\
 +The 243Ohm shunt (R311) is not assembled by default. it can be used to transform th einputs to sense current signals such as 4-20mA norm signals.\\
 To adapt for high impedance signal sources, current sources or other special signal sources, please contact Schmid-Electronik for advice. To adapt for high impedance signal sources, current sources or other special signal sources, please contact Schmid-Electronik for advice.
