1-Pole Connection
For 1-pole applications, all 8 positive-switching and all 8
negative-switching outputs are available, for a total of 16 outputs. If
you are using a positive-switching output, connect the other side of
the output to S-. If you are using a negative-switching output, connect
the other side of the output to S+.
Line monitoring with a 1-pole connection is not possible.
For 1-pole connections, inductive loads can be connected without a
protection diode on the load, because there is a protection diode
located within the GuardPLC module. However, Rockwell Automation
strongly recommends that a protection diode be fitted directly to the
load to suppress any interference voltage. A 1N4004 diode is
recommended.
ATTENTION
You must not connect the positive-switching output directly to
an external L- load or connect the negative-switching output
directly to an external L+ load. You must use the S+ and S-
terminals.
