Steady-state current: Max. 15 mA
Current during FlashROM blanking time: Max. 15 mA
Fieldbus Foundation download class: Class 1
Class 1 devices can continue the specied measurement and/or control actions even while software
is being downloaded to them. Upon completion of a download, however, the devices will be reset
internally to make the new, downloaded software take effect, and this will temporarily halt eldbus
communication and function block executions.
