A 2-wire irrigation decoder controller is a type of irrigation system used to manage multiple irrigation valves with minimal wiring, offering significant advantages in large or complex irrigation setups.
Unlike traditional irrigation controllers, which use a separate wire for each valve, a 2-wire system uses just two main wires to communicate with multiple irrigation valves. The "decoder" is a device attached to each valve, allowing the controller to send signals over the two-wire path to control individual zones.
