5.1.3. Analog Inputs
The module is equipped with two unipolar analog inputs protected by diodes. Po-
wer supply to the sensors is from an external source. The analog current and volt-
age values are accessible via the CoDeSys controller configuration.
Input channel data
Current measurement
Nominal input current value 0..20 mA
Maximum input current value 40 mA (Ue = +24 V)
Voltage measurement
Nominal input voltage value 0..10 V
Maximum input voltage value 12 V
General data
Input filter, 1
st
order
τ = 1ms for current
τ = 10ms for voltage measurement
Conversion method Successive approximation, no error
codes
Resolution 10 bit; 1 LSB = 78.1 µA / 39.06 mV
Accuracy within the 0...50 °C tempera-
ture range
2 LSB; +/- 1 %
Pole reversal protection Yes
Sampling rate approx. 1 ms
Due to internal protective circuitry, the load is nonlinear for current operation.
