WIRING QUAD PAK MODULES
This section lists all quad pak modules and provides wiring diagrams for both input and output modules.
Each quad pak I/O module consists of two pairs of circuits. These circuit pairs share a common point.
A quad pak module connects to four numbered terminals and two common (“C”) terminals, as follows:
• Terminal 1 and the upper C terminal correspond to a circuit in channel 0.
• Terminal 2 and the upper C terminal correspond to a circuit in channel 1.
• Terminal 3 and the lower C terminal correspond to a circuit in channel 2.
• Terminal 4 and the lower C terminal correspond to a circuit in channel 3.
For polarized modules, the positive connection goes to the C terminal and the negative connection goes
to the numbered terminal.
Input Modules
Use Figure 2-32 to wire the quad pak DC and AC input modules listed in Table 2-17. The diagram shows
a DC input module wired to channels 16–19 and an AC input module wired to channels 0–3 on a
PB16HQ rack.
For the quad pak input modules listed in Table 2-17, the input device may be wired to either terminal.
The polarity of the power does not matter for any of the modules.
