Technical Data of the analog inputs
Data Value
Connections X2 / 2.0, X2 / 2.1, X2 / 2.2, X2 / 2.3, X3 / 2.4,
X3 / 2.5, X3 / 2.6, X3 / 2.7
Reference connections (AGND) X2 / 1.0, X2 / 1.1, X2 / 1.2, X2 / 1.3, X3 / 1.4,
X3 / 1.5, X3 / 1.6, X3 / 1.7
Type of inputs Voltage bipolar, current unipolar
Time constant of the input filter Voltage
Replacement device: 100 µ s
Existing device: 470 µ s
Conversion cycle *) Replacement device: 2 ms (over 8 8
outputs)
Existing device: 8 ms
Resolution: range
±
10 V Replacement device: 2.4 mV, 12 bit + sign
Existing device: 5 mV, 11 bit + sign
Protection against reversed voltage Yes
Overvoltage protection Up to 30 V DC
*) Conversion cycle of S500 module AX522. The transmission via serial buses is slower.
Unused voltage inputs must be configured as current inputs (due to wire-break
detection AX522 S500 module).
