For a number of controller models, the station provides a power monitoring component to track its AC power and backup battery
level, with a configurable delay for orderly shutdown of the controller upon AC power failures. You access power monitoring
in the PowerMonitorService in a running station.
JACE-6 and JACE-7 controller models use an onboard NiMH backup battery (nickel metal hydride), to preserve runtime data, and also allow continuous
operation during brief power outages. The JACE-3E and JACE-6E controllers use integral SRAM to back up 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 upport an additional external 12V SLA (sealed lead acid) battery for backup usage.
NOTE: The JACE-8000 controller has no backup battery. Instead, onboard SRAM preserves runtime data upon any power event. Thus, its station’s
PlatformServices has no PowerMonitorService. For continuous operation across power events, an external battery-backed UPS must be used to power the controller.
