The following rule applies if connecting CUS71D sensors:
• CM442R
– Only one CUS71D is possible; an additional sensor is not permitted.
– The second sensor input may also not be used for another type of sensor.
• CM444R
No restrictions. All the sensor inputs can be used as required.
• CM448R
– If a CUS71D is connected, the number of sensor inputs that can be used is limited to a maximum
of 4.
– Of these, all 4 inputs can be used for CUS71D sensors.
– Every combination of CUS71D and other sensors is possible, provided that the total number of
connected sensors does not exceed 4.
Connection
Sensor cable connected directly to the terminal connector of the sensor module 2DS or of the basic
module L, H or E (→  20 ff.)
