Rockwell Automation Publication 1440-IN001B-EN-P - October 2013
21 Buffer/Xducer Pwr
(-) Provides negative (-24...9V) 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 bias transducers or terminal 21 for
negative bias 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 24V In (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 24V Common (terminals 43 and 45)
Used to daisy chain power if XM modules are not plugged into each other
