2-2 Installing And Wiring Your Module
Power Requirements
The module receives its power through the SLC 500 chassis backplane
from the fixed or modular +5 V dc/+24 V dc chassis power supply.
The maximum current drawn by the module is shown in the table
below.
Maximum Current Drawn by the Module
Considerations for a Modular System
Place your module in any slot of an SLC 500 modular, or modular
expansion chassis, except for the left-most slot (slot 0) reserved for
the SLC processor or adapter modules.
When using the module with a modular system, add the values shown
above to the requirements of all other modules in the SLC to prevent
overloading the chassis power supply. Refer to the SLC 500 Modular
Hardware Style User Manual, publication 1747-UM011.
