A1 

TEMP-

Temperature Sensor Reference–This pin is tied to the
temperature sensor reference in the terminal block and to
the isolation amplifier negative input in the module.

A3

TEMP+

Temperature Sensor Output–This pin connects the
temperature sensor output to the amplifier input selector.

A7

+5 V

+5 VDC Isolated Source–This pin, which powers the
temperature sensor on the terminal block, has 0.5 mA of
source not protected.

A11

VEX/2

Half Voltage Excitation Output–This pin connects to the
internal bridge completion network for quarter-bridge and
half-bridge measurements. Protected to 

±

20 V maximum.

A13

VEX-

Negative Voltage Excitation Output–This pin is connected
to the voltage excitation negative output.

A15

SENSE-

Negative Voltage Sense–This pin must be tied to VEX- at
the load for remote sensing. When using the SCXI-1322
terminal block, this pin is connected to VEX/SENSE-
screw terminals.

A17

SENSE+

Positive Voltage Sense–This pin must be tied to VEX+ at
the load for remote sensing.  When using the SCXI-1322
terminal block, this pin is connected to VEX/SENSE+
screw terminals. This pin is not protected.

A19

VEX+

Positive Voltage Excitation Output–This pin is connected
to the voltage excitation positive output.

A21

IEX-

Negative Current Excitation Output–This pin is connected
to the current excitation negative output.

A23

IEX+

Positive Current Excitation Output–This pin is connected to
the current excitation positive output.

A5, A9,

No Connect–Do not connect any signal to these pins.

A25-A29
