This equipment is classified as open equipment and must be mounted
in an enclosure during operation to provide safety protection.
The analog output module receives its power through the 1771 I/O
chassis backplane from the chassis power supply. It does not require
any other external power supply. When planning your system, you
must consider the power usage of all modules in the I/O chassis to
prevent overloading the I/O chassis backplane and/or power supply.
Add this to the requirements of all other modules in the I/O chassis.
Analog Module Power Requirement
1771ĆOFE1
1 5A @ 5V dc
1771ĆOFE2
1.5A @ 5V dc
1771ĆOFE3 2.5A @ 5V dc
!
ATTENTION: Do not insert or remove modules
from the I/O chassis while system power is ON.
Failure to observe this rule could result in damage to
module circuitry.
