Cable length: 150 m
The longer the cable, the weakerthe analog voltage signalbecomes.
A very long analog signal cable iseasily affected by other electricalsignals resulting in a weaker signal.
Cable length: 0 m
Cable length: 50 m
1 Extending an analog signal cable leads to greater interference anda weaker signal

Controlling multiple analog devices requires extensive wiringCurrent Problems
A single cable permits processing of up to 128 channelsVisual Analog Solution

When the number of analogdevices increases, so doesthe wiring.
Only one cable isneeded to connectthe analog units,allowing up to 128channels of analogI/O control.
