Considerations for a Modular System
Place your module in any slot of an SLC 500 modular, or modular
expansion chassis, except for the leftmost slot (slot 0) reserved for the
SLC processor or adapter modules.
Considerations for a Fixed Controller
The power supply in the two slot SLC 500 fixed I/O chassis (1746-A2)
can support only specific combinations of modules.
Refer to the table at the left or to the Chart Method below to
determine whether the power supply can support the pair of modules.
Chart Method
Follow these steps to use the chart to determine a valid pair of
modules.
1. For both modules, add the current rating at 5V dc and again at
24V dc.
2. On the chart, draw a horizontal line for the total 5V dc current
rating.
3. On the chart, draw a vertical line for the total 24V dc current
rating.
4. Observe the intersection; if within the chart boundary, the pair
is OK.
