Sensor Power Supply
Features
Characteristics
Sensor power supply channels
4, separate per input channel
Output voltage
Each channel can be set separately:
“Off”, in steps (5 V, 8 V, 10 V, 12 V,
15 V) or freely selectable as a value in
the range 5 V to 15 V
D/A converter
16-bit (resolution 229
V)
Protection
Outputs (plus) short-circuit proof
against ground and up to 26 V over
-
voltage.
Ground connected to operating volt
-
age ground and protected by a fuse.
Diagnostics
Short-circuit detection per channel;
overload conditions reduce the output
