EX2 expansion modules
You can add up to four EX2 expansion modules to a Tracer MP581

Tracer MP581:
• Six universal inputs
• Four binary outputs
• Four analog outputs
The EX2 is available in two packages:
• Frame-mount with plastic cover (4950 0499)
• Metal enclosure (4950 0500)
Figure 2 illustrates the two packages. For dimensions and other informa-
tion, see Chapter 13, “Installing EX2 expansion modules.”
