Usable sensor characteristics
o Output between +SIG and −SIG: ±3.2 mV/V or less
o Voltage (current) between +EXC and −EXC: 10V DC, 5V DC
or 2.5V DC ±10% (30mA maximum current)
ATTENTION
Do not connect sensors that do not meet the rated output
(output between +SIG and −SIG) and the maximum safe exci-
tation voltage (voltage between +EXC and −EXC) specifications.
NOTE
If not using the TEDS function, terminals 1 and 2 can be left
open.

3-3. Displacement sensor

Power is only output (voltage or pulse) for the displacement
sensor selected with INPUT MODE on the DISPLACE. SENSOR
settings screen (page 41).
+12V is output when voltage is selected, and +5V is output
when pulse is selected.

3-3-1. Displacement sensor (voltage)

The +12V power supply of pin 10 can be used as a 250mA
(maximum) power supply for a displacement sensor (voltage).
