Chapter 1: Introducing NLC‐100SH
The NLC is a microprocessor based irrigation control system. A central
controller and up to 100 field stations comprise a complete system. In
addition the controller will accept input from several external sensors in
order to adjust its irrigation to the local weather conditions.
The NLC controls up to 100 solenoids attached to valves or relays via the
built‐in connection board and three expansion boards.
In addition communication between the controller's 3D and the stations
happens over a two‐wire path. Depending on the signal from the
controller's 3D, the stations each activate or deactivate a valve. The
controller's 3D signals to the stations based on configurable schedules,
eliminating the need for human interaction when the park, garden or other
surroundings need watering ‐ once set up, the NLC runs on its own.
The Two‐wire Technology
The NLC uses two‐wire transmission technology to tell the stations when to
act. This means that instead of laying out a cable to each individual valve,
just one or two single cables are laid out, and the stations all connect to the
same cable(s):
