Power Requirements

The RTD module receives its power through the SLC500 chassis backplane
from the fixed or modular +5V dc/+24V dc chassis power supply. The
maximum current drawn by the module is shown in the table below.

When you are using a modular system configuration, add the values shown in
the table above to the requirements of all other modules in the SLC chassis to
prevent overloading the chassis power supply.

When you are using a fixed system controller, refer to the Important note about
module compatibility in a 2-slot expansion chassis on page 2-4.
