Product Description:

The measuring ranges of the analog input channels Resolution in the PLC system:The measured values are converted with a resolution of 12 bits, i.e. 11 bits plus sign for voltage and 12 bits without sign for current. The ranges 0...5 V und ±5 V are converted with 10 bits plus sign.Examples:
Measuring range Range of numbers Further details can be found in volume 2, chapter 5.1 "General
information for the use of analog inputs and outputs".In order to make sure, that unused input channels have a defined 0V level, they may be shorted to AGND. Unused inputs must be configured with "unused".
The relationship between the analog input signals and the converted numbers is illustrated in the following figures.

Product's Character:

Input currents that exceed the measuring range cause the overflow numerical value of +32767. If the measured value is below the range, the underflow numerical value of -32767 is set.The input impedance is ca. 330 Ω. The current input has a self-protecting mechanism. If the input current gets too
high, the shunt is switched off and the value for range overflow is generated. About every second, the unit tries to switch on the shunt again. In this way the correct measurement will succeed after the current has reached a normal value again.The trigger of the self-protecting mechanism is displayed
by the red LED Ovl as long as the overload is present. In the PLC system an error message is then stored (FK4,error number 4).The open-circuit monitoring begins below ca. 3 mA.
