Max. connectable cross-section: 1.5 mm²
Type: Screw terminal 1 (refer to Appendix A)
1) AI: analog inputs; P10/N10: auxiliary voltage; M or GND: ground reference
Caution
If more than 40 mA flows through the analog current input, then the component could be
destroyed.
The common mode range may not be violated. This means that the analog differential
voltage signals can have a maximum offset voltage of +/-30 V DC with respect to the ground
potential. If the range is infringed, incorrect results may occur during analog/digital
conversion.
