Connecting the CBS105.1-2 Smart Lambda Sensor Cable
The CBS105.1-2 Smart Lambda Sensor Cable must be connected as passive 2-
wire measuring transformer with additional voltage supply for the current inter
-
face (see Fig. 2
3 on page 15). An additional external power supply or a voltage
supplied by the PLC can be used for the voltage supply of the current interface
(loop supply) of the Smart Lambda Sensor Cable.
2.2.4.1
Output signals and measure variables
Supply with DC voltage
If the Smart Lambda Sensor Cables CBS100.1-2 and CBS105.1-2 are supplied
with DC voltage, the wiring of the "CONFIG" connection allows selecting to
which measure variable the signal issued at the "AOUT" connection is assigned
(see chapter 4.3.4 on page 29).
TIP
Operating the current interface ("AOUT" output) of the CBS105.1-2 Smart
Lambda Sensor Cable requires an additional voltage supply. The current
interface is not supplied via the voltage supply of the Smart Lambda Sensor
Cable (connections "AC1" and "AC2"!
