Indication of the input signals One LED per channel
Conversion cycle 2 ms (for 8 inputs + 8 outputs), with Pt/Ni... 1 s
Resolution Range 0 V...10 V: 12 bits
Range -10 V...+10 V: 12 bits + sign
Range 0 mA...20 mA: 12 bits
Range 4 mA...20 mA: 12 bits
Conversion error of the analog values
caused by non-linearity, adjustment error
at factory and resolution within the normal
range
Typ. ±0.5 % of full scale
at 25 °C
Max. ±1 % of full scale (all ranges)
at 0 °C...60 °C or EMC disturbance
Relationship between input signal and hex
code
See table, Ä Chapter 1.5.2.2.4.9.1 “Input Ranges
of Voltage, Current and Digital Input” on page 537
Unused voltage inputs Are configured as "unused"
Unused current inputs Have a low resistance, can be left open-circuited
Overvoltage protection Yes
