Figure 5-21: Wire-Shield Grounding
To facilitate module replacement, it is advisable in most cases to route
all wiring through either the top or the bottom of the terminal block.
This allows the terminal block to pivot up or down, allowing ready
access to the module, and is the preferred method for a limited
number of wires.
For a larger number of wires, or for wires of a heavier gauge, it is
advisable to route some wires through the top of the terminal block,
and some through the bottom, as indicated in
Wire-Shield Grounding
section. In this case, it is necessary to adjust wire length so as to
ensure adequate flexibility of the twisted wires and to provide
clearance sufficient to remove the I/O module.
UIO module wiring
It is 16 Channel universal I/O module, and each channel can be
configured for AI, AO, DI and DO. The UIO is sourcing type.
