5.3.6 User I/O Connections
The user I/O is a standard interface for automation, provided on the power supply. It
provides the ability to make your own interface for your automation, special control, or
reporting needs. The interface cable has a 26-pin HD male D-Sub connector on one end,
and wires on the other end. Pins are wired to ICEA standard color code (see Figure 5.8
User I/O Cable Identification and Wire Color Diagram and Table 5.5 User I/O Cable Pin
assignments).
Digital I/O functions can be configured to either active-high or active-low using the DCX S
Power Supply Web Page Interface. Tables Table 5.6 Available Digital Input Functions to
Table 5.9 Available Analog Output Functions list the input and output functions available
on the DCX S Power Supply. See table Table 5.10 Default User I/O Connector Pin
Assignments for the default user I/O pin assignments.
Figure 5.9 Typical Digital I/O Wiring Examples and Figure 5.10 Typical Analog I/O Wiring
Examples show typical wiring examples.
For complete instructions detailing the web page interface consult the DCX S Power
Supply Web Page Interface Instruction Manual (100-412-187).
NOTICE
Ensure all unused wires are properly isolated. Failure to do so may
result in a power supply malfunction.
