Table 4 - Configuring Buffered Output Input Range
Connect the Transducer
The XM-124 module can accept inputs from any Allen-Bradley non-contact
eddy current probe, a standard IEPE accelerometer, a velocity transducer, AC
voltage output, or a DC voltage output measurement device.
Connect an IEPE Accelerometer
The following figures show the wiring of an IEPE accelerometer to the terminal
base unit.
IMPORTANT The voltage operating range of the buffered outputs must be configured to
coincide with the corresponding transducer bias range. This operating
range is configured by placing a jumper from terminal 5 (channel 1) and
terminal 22 (channel) to either terminal 6 (Positive Buffer Bias) or terminal
21 (Buffer -), depending on the transducer. See
Table 4 . The buffered
output operating range is configured independently per channel.
Transducer Input Range Channel Connect Terminal To Terminal
Negative Bias -24…9V 1 5 21
2 22 21
Positive Bias -5…24V 1 5 6
2 22 6
Non-Bias -5…9V 1 ---- ----
2 ---- ----
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 27 ).
IMPORTANT The internal transducer power supply is providing power to the IEPE
accelerometer. Make certain the IEPE Power parameter is enabled. Refer
to
Transducer Object (Class ID 328H) on page 154 .
IMPORTANT A jumper from terminal 5 to terminal 6 is required for channel 1 buffered
output. A jumper from terminal 22 to terminal 6 is required for channel 2
buffered output. See
Connect the Buffered Outputs on page 33 .
