Grounding the Module
This product is intended to be mounted to a well-grounded mounting surface
such as a metal panel. Additional grounding connections from the module’s
mounting tabs or DIN rail (if used) are not required unless the mounting surface
cannot be grounded. Refer to
Industrial Automation Wiring and Grounding
Guidelines
, Allen-Bradley publication 1770-4.1, for additional information.
Input Type Selection
Select the input type, current or voltage, using the switch located on the module’s
circuit board
and
the input type/range selection bits in the Configuration Data
File (see page 16). You can access the switch through the ventilation slots on the
top of the module. Switch 1 controls channel 0; switch 2 controls channel 1. The
factory default setting for both switch 1 and switch 2 is Current. Switch positions
are shown below.
Output Type Selection
The output type selection, current or voltage, is made by wiring to the
