IMPORTANT: For single-ended
connections, remember the
following:
• For both input types, we
recommend that you use
Belden #8761or equivalent
cable.
• The mV ranges with the
Voltage input type do not
support single-ended
encoder wiring.
• All commons are electrically
tied together in the
controller.
• If multiple power supplies
are used, the commons
must have the same
reference.
