M4RTU/M4 I/O User’s Guide 65
WIRING DIGITAL 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. This wiring scheme is identical for the M4RTUX, starting with channel 8.
Input Modules
Use Figure 5-4 on the following page to wire the digital DC and AC input modules listed in Table 5-1. The
diagram shows a DC input module wired to channel 0 and an AC input module wired to channel 1 on the
M4RTU/M4 I/O.
For the digital input modules listed in Table 5-1, the input device may be wired to either terminal. The polarity
of the power does not matter except for the G4IDC5K and G4IDC5D.

Output Modules
Use Figure 5-4 to wire the digital DC and AC output modules listed in Table 5-2. The diagram shows a DC output
module wired to channel 6 and an AC output module wired to channel 7 on the M4RTU/M4 I/O.
For the digital output modules listed in Table 5-2, the load may be wired to either line.
