Fig. 11 24 VDC and sensor connection
In some applications it may be required to measure both pressure and flow,
but not temperature. The converter can supply two sensors and thus convert
signals from them. However, this requires that two conductors are mounted
in each of terminal 11 and 12. See fig. 12.

Terminal Description
1 External 24 VDC supply (PELV-approved)
2 Earth from external 24 VDC supply (PELV-approved)
8 Green diode which is on when SI 010 CNV is on
9 Sensor input 1 (yellow/white if a standard cable is used)
10 Sensor input 2 (yellow/white if a standard cable is used)
11 Earth for sensor (green if standard cable is used)
12 + 5 V supply for sensor (brown if standard cable is used)
