Battery Life Advisory
Note: Modules manufactured after April 1st, 2011 do not contain a battery. For modules manufactured before that
date the following applies:
The module uses a rechargeable Lithium Vanadium Pentoxide battery to back up the real-time clock and CMOS
settings. The battery itself should last for the life of the module. However, if left in an unpowered state for 14 to 21
days, the battery may become fully discharged and require recharging by being placed in a powered-up ControlLogix
chassis. The time required to fully recharge the battery may be as long as 24 hours.
Once it is fully charged, the battery provides backup power for the CMOS setup and the real-time clock for
approximately 21 days. Before you remove a module from its power source, ensure that the battery within the module
is fully charged (the BATT LED on the front of the module goes OFF when the battery is fully charged). If the battery
is allowed to become fully discharged, the module will revert to the default BIOS and clock settings.
Note: The battery is not user-replaceable or serviceable.
Electrical Ratings:
Backplane current load: 800mA @ 5 VDC; 3mA @ 24 VDC
