Connecting the Transducer

The XM-122 can accept input from any Allen-Bradley non-contact eddy
current probe, a standard IEPE accelerometer, or a DC voltage output
measurement device such as a velocity or pressure transducer.

Connecting an IEPE Accelerometer

Figures D.2 and D.3 show the wiring of an IEPE accelerometer to an earlier
revision of the XM-122 module (before revision D01).

Figure D.2 IEPE Accelerometer to Channel 1 Wiring

ATTENTION

You may ground the cable shield at either end of the cable.
Do not ground the shield at both ends. Recommended
practice is to ground the cable shield at the terminal base
and not at the transducer. Any convenient Chassis terminal
may be used (see Terminal Block Assignments on page
179).

IMPORTANT

The internal transducer power supply is providing power to
the IEPE accelerometer. Make certain the IEPE Power
parameter is enabled. Refer to Channel Transducer
Parameters on page 58.
