Abstract
A solid state control system for large-scale irrigation is disclosed. The system incorporates a central processing unit having a master clock and a central/syringe timing module system connected to a plurality of satellite controllers which are, in turn, connected to control irrigation solenoid valves. The satellites are operable on an individual basis from internal clocks and data or externally in response to multiplexed signals from the central processing unit generated by the comparison of the master clock to unique individually identified groups of data.
