Install the XM-124 Standard Dynamic Measurement Module Chapter 1
1 Terminals are internally connected and isolated from the chassis terminals.
20 Tachometer (-) Tachometer transducer/signal return, TACH Buffer return
21 Buffer/Xducer Pwr (-) Provides negative (-24 V to +9 V) voltage compliance to buffered outputs
Connect to terminals 5 (CH 1) and 22 (CH 2) for negative bias transducers
Transducer power supply output, negative side; used to power external sensor (40 mA maximum
load)
22 Buffer Power 2 IN Channel 2 buffer power input
Connect to terminal 6 for positive biased transducers or terminal 21 for negative biased
transducers
23 CAN_High DeviceNet bus connection, high differential (white wire)
24 CAN_Low DeviceNet bus connection, low differential (blue wire)
25 +24 V Out Internally connected to 24 V In 1 (terminal 44)
Used to daisy chain power if XM modules are not plugged into each other
If power is not present on terminal 44, there is no power on this terminal
26 DNet V (+) DeviceNet bus power input, positive side (red wire)
27 DNet V (-) DeviceNet bus power input, negative side (black wire)
28 24 V Common 1 Internally connected to 24 V Common (terminals 43 and 45)
Used to daisy chain power if XM modules are not plugged into each other
29 4…20 mA 2 (+) 4…20 mA output
300 ohm maximum load
30 4…20 mA 2 (-)
