Full bridge signal connection
6-wire and 4-wire sensor connection
Voltage or current excitation is allowed.
Sense terminals have to be connected to excitation also when 4-wire connection is used.

Potentiometric Sensor
200 Ohm to 10 kOhm
Half bridge signal connection
5-wire and 3-wire sensor connection, potentiometric sensors
Sense terminals have to be connected to excitation also when 4-wire connection is used.
A potentiometer works like a half bridge sensor with ±500 mV/V sensitivity. The scaling is:
0 % position equals -500 mV
100 % position 500 mV
3-wire connection
5-wire connection

'R+' has to be connected only if shunt check is required, otherwise it can be left unconnected.
