Fitted onto each logger is an onboard 24V 30mA power generator. The Cumulus Logger can generate a stable 24V output at
a maximum of 30mA, allowing for the powering of an external piece of equipment or current loop device eliminating the
need for a secondary power supply. This option will also function under battery operation.
