The PACIO Counter/Enc Module has two identical channels with the same connections listed in the above
table.
The Controller and I/O modules have been tested to comply with international electromagnetic and
emission standards. To reduce radiated emissions, ensure that there is a good earth connection to the
PAC, which can be accomplished by attaching the DIN rail to a suitable Earth ground and also utilizing
Pin-3 on the Controller DC power input connector. This connection must be made with the shortest
possible, heavy gage wire or braided cable. Low-resistance (<0.5 ohms) continuity should be verified with
an ohmmeter for proper grounding. In addition, all communication cables should be shielded and
