ical connection
Pin assignment X1/X2
Optional: Analog module with ±10 V interface at input X1 or X2
for connecting an analog sensor
For example, you can connect an analog linear encoder to this
connection, or a temperature sensor with a voltage interface to X2.
The ND converts the voltage value to a readable measured value.
A separate description of the analog module is included with the
module.
