This configuration's controllogix xt power supply is the attribute that drives the replacement decision. A power supply or battery in a controller rack is sized against the backplane budget, not in isolation. controllogix xt power supply is whether the unit delivers the voltage and current the rack draws at full load, and whether the battery holds programme and configuration through a power loss. Checking 5.51 x 4.41 x 5.71 in (14.0 x 11.2 x 14.5 cm) against the rack's requirement prevents a supply that fits the slot but cannot hold the load.
