Sensor Wiring (continued)
4-Wire Sensor
There is only one way to wire a 4-wire sensor to an ANR2.
Figure 3.8 4-Wire LVDT/RVDT Wiring
5-Wire Sensor
Five wire sensors can be wired as either differential sensors or ratiometric sensors. Ratiometric wiring is less
sensitive to temperature variations, but the sensor must be manufactured for use as a ratiometric sensor. Con-
tact your sensor’s manufacturer if you are not sure which type of sensor you have.
Differential Wiring
Five wire sensors can be used as 4-wire sensors by leaving the centertap wire unconnected and electrically
isolated. As shown in the diagram below, you have the option of landing the centertap wire on one of the
N.C. pins of the ANR2 connector.

NOTE: This is a signal ground, not a shield ground.
All shields must be connected to J1-2 or the
earth ground connection of the ANR2 module.
NOTE: Connection bExc output voltage and A input.
LVDT/RVDT
Sensor
NOTE: Shields are typically grounded at the ANR2.
Verify that the shields are not connected to the sensor
body. If they are, and the body of the sensor is grounded,
do not attach the shields to the ANR2 if the sensor and
ANR2 do not
. share a common ground

Connection bExc output voltage and A input must be made.
The sensor’s output centertap wire is not used and must remain electrically isolated. The wire can
be left unconnected or landed on pins J1-9 or J1-10.
This is a signal ground, not a shield ground. All shields must be connected to J1-2 or the earth
ground connection of the ANR2 module.
