CONNECTING FIELD WIRING
This section provides detailed information on wiring digital, quad pak, and analog I/O modules to Pamux
systems. It includes examples of how to wire all currently available Pamux-compatible modules. For a
complete list of all modules that can be used with Pamux systems, see Appendix B.
WIRING DIGITAL MODULES
This section lists all Pamux-compatible digital modules and provides wiring diagrams for both input and
output modules.
Each digital I/O channel has two terminals corresponding to each installed digital module. Terminals 1
and 2 correspond to a module in channel 0, terminals 3 and 4 correspond to a module in channel 1, and
so on. For polarized modules, the positive connection goes to the first terminal of the pair and the
negative connection goes to the second.
Input Modules
Use Figure 2-31 to wire the digital DC and AC input modules listed in Table 2-15. The diagram shows a
DC input module wired to channel 0 and an AC input module wired to channel 1 on a G4PB16H rack.
For the digital input modules listed in Table 2-15, the input device may be wired to either terminal. The
polarity of the power does not matter except for the G4IDC5K, G4IDC5D, and IDC5D.
