Understanding Your SLC 500/1746 Control System
This appendix provides information on using SLC 500/1746 control systems. Topics
include:
•
selecting your SLC 500/1746 control power supply
•
system installation recommendations
•
mounting your control system
•
installing your I/O modules
•
wiring the I/O modules
•
calculating heat dissipation for your control system
When configuring a modular system, you must have an individual power supply for
each chassis. Careful system configuration results in the best performance. Excessive
loading of the power supply outputs can cause a power supply shutdown or
premature failure.
Selecting Your
SLC 500/1746
Control Power
Supply There are three different ac power supplies and four dc power supplies. For ac power
supplies, the 120/240V selection is made by a jumper. Place the jumper to match the
input voltage. The power supply has an LED that illuminates when the power supply
is functioning properly. On the following page are the general specifications for the
power supplies.
