Conventional Layout; The Controller - Netafim NLC-100SH Installation & Troubleshooting Manual

In contrast, this is how the above system would look using a conventional
irrigation system that needs a dedicated cable to each individual valve:
Conventional layout:
The two‐wire technology has several obvious advantages over a
conventional system:
• Ease of installation:You are only handling one roll of wire.
• Ease of expansion: When you need to add a station in the field, you
don't have to dig in a new cable and risk damaging the existing web
of cables already in the ground ‐ you simply attach the new station
to the existing cable.
Cost reduction: You save money on expensive copper cable ‐ using 20%
compared to traditional cabling.
The Controller
The heart of a NLC based system is the controller. This is a microprocessor
controlled device that stores your irrigation programs and NLC individual
stations in the field when to activate their valve(s).
