Calculate Power
Requirements

The module receives its power through the 1771 I/O chassis backplane from
the chassis power supply. The module requires 225mA from the output of this
supply .

Add this current to the requirements of all other modules in the I/O chassis to
prevent overloading the chassis backplane and/or backplane power supply.

ATTENTION

Do not insert or remove modules from the I/O chassis
while system power is applied. Failure to observe this rule
could result in:

• module damage or degradation of performance
• injury or equipment damage due to possible

unexpected operation.
