5.8.2 Ain/Aout Card
With the above card, the XTE3000 is provided with a 4-20 analog input and a 4-20 mA analog
output. This card should be plugged on the base card, replacing the “TERMINAL BOARD
ADAPTOR” card supplied as standard. A hardware alarm is generated if the XTE3000 was set
to be equipped with an Ain/Aout card and the card is damaged or missing.
An Ain/Aout REPORT is also present in the list of reports if the card is present (see Section 6).

• 4-20 mA analog output
The 4-20 mA output can be congured to provide a signal proportional to either
“position” or “torque”. The polarity option allows the relationship between
position (or torque) and the 4-20mA output signal to be reversed and the 4-20 mA
output signal. See “VIEW and SET-UP” features (Section 9.1.9, OUT 4-20 mA).
The 4-20 mA output is optically-isolated (opto-coupled). It should be powered by
a 20-30 V DC voltage (externally or internally generated) and the maximum load
(including cable resistance) should be less than 300 ohm.
Figure A shows the wiring diagram.
