Wiring Information
The H2-CTRIO(2) module has two
independent input channels, each consisting of
four optically isolated input points (pts. 1A-1D
on common 1M and pts. 2A-2D on common
2M). The inputs can be wired to either sink or
source current.
The module has four optically isolated output
points (Y0-Y3 with isolated commons C0-C3,
respectively) that can be wired to either sink
or source current. Remember that the internal
jumpers can be used to connect the input
commons or output commons together.
NOTE:
Field device wiring must be compatible with the module configuration configured in Do-more
Designer
DC type field devices are configured to either sink or source current. This affects the wiring of
the device to the CTRIO module as seen below.
When wiring CTRIO(2) modules, please consider the following:
•
Keep encoder input wiring as short as possible
•
Route wiring to avoid any runs parallel to noisy cables.
•
Route wiring to avoid the proximity of noisy devices.
•
Use shielded, twisted pair cables, such as:
