2408 and 2404 Controller A-1
Appendix A
UNDERSTANDING THE ORDERING CODE
The 2408 and 2404 controllers have a modular hardware construction, which accepts up to
three plug-in Input/Output modules and two communications modules to satisfy a wide range
of control requirements. Two digital inputs and an optional alarm relay form part of the fixed
hardware build.
The ordering code is in two parts. The hardware coding and an optional configuration
coding. The hardware coding specifies the basic build of the controller and the plug-in
modules that are fitted.

The controller may have been ordered with just the hardware build specified, or with
configuration included. This is indicated by the ordering code on the side of the controller.
