Backup Battery (or not)

JACE-6 and JACE-7 controller models use an onboard NiMH backup battery (nickel metal hydride), used to preserve runtime data, and also allow continuous operation during brief power outages. The JACE-3E and JACE-6E controllers use integral SRAM to backup runtime data, but can also optionally use an onboard NiMH battery for continuous power event operation. The JACE-7 and JACE-603/JACE-645 models also support an additional external 12V SLA (sealed lead acid) battery for backup usage.

For any of the above controller models, the JACE station provides a “power monitoring” component to track its AC power and backup battery level, with a configurable delay for orderly shutdown of the JACE upon AC power failures. Access power monitoring of a JACE in the PowerMonitorService in a running station. See “About Platform Services”.
