Chapter 8 Wire and Configure the 1753-IB16XOB8 Module

2-Pole Connection

If the outputs are configured for 2-pole operation, 8 outputs are
available. Each of the 8 outputs switch both L+ and L-. 2-pole outputs
(without line monitoring) are wired to both the positive-switch and
negative-switch of a single channel, 2+ and 2- for example.

IMPORTANT

The corresponding channels for 2-pole connections must be
configured for 2-pole operation by using the system variable
DO[xx].2-pole. See

Appendix B

for more information on system

variables.

ATTENTION

The positive-switching output must be wired to an output along
with the corresponding negative-switching output of the same
channel. Negative- or positive-switching outputs must not span
different channels unless they are connected in pairs (see

3-pole Connection With Line Monitoring

on page

89

).

ATTENTION

Inductive loads must be connected with a protection diode on
the load in 2-pole operation.
