2.3 General installation data
2.4 SM 111
The SM 111 is used for the collection and transfer of
sensor data. The SM 111 works together with the
IO 111* as shown below.
Fig. 2
IO 111 and SM 111
* Only IO 111 versions with communication module,
part number 96177804.
The SM 111 can collect data from
•
3 current sensors, 4-20 mA
•
3 Pt100 thermal sensors
•
1 Pt1000 thermal sensor
•
1 PTC thermal sensor
•
1 digital input.
