Time constant of the input filter Voltage: 100 µs
Current: 100 µs
Indication of the input signals 1 LED per channel (brightness depends on the
value of the analog signal)
Conversion cycle 1 ms (for 4 inputs + 2 outputs); with RTDs Pt/
Ni... 1 s
Resolution Range 0...10 V: 12 bits
Range -10...+10 V: 12 bits + sign

Conversion error of the analog values
caused by non-linearity, adjustment error at
factory and resolution within the normal
range
Typ. 0.5 %, max. 1 %
