Determining Power Requirements
Tables 3-1 and 3-2 are provided for calculating
the total current requirements for those parts of
the system requiring battery backup.
Table 3–1—Standby Current Requirements at 24 Vdc
Notes: Standby current is the average current draw for the device in normal mode.
This table is for battery calculations only.
For OPECL standby current requirements, reference versions 16.1 and earlier of this manual.
