The K-Rain PRO-EX3 2-Wire Single Station Decoder (3311) enables efficient, scalable irrigation control by integrating individual zones into a 2-wire system. Designed for use with the PRO-EX3 controller, this decoder allows a single station valve to be controlled remotely along a shared 2-wire path—eliminating the need for dedicated wire runs to each valve.

Using advanced decoder technology, the 3311 receives communication signals from the controller over a two-conductor wire path and activates the assigned valve based on programmed irrigation schedules. This approach significantly reduces installation time, material costs, and trenching requirements compared to traditional multi-wire systems.

The PRO-EX3 2-wire system supports flexible expansion, allowing additional decoders to be added anywhere along the wire path to grow irrigation capacity without major system changes. Each decoder is easily assigned to a specific station through the controller interface, simplifying setup and system management.

Ideal for residential, commercial, and retrofit applications, the 3311 decoder delivers reliable performance, simplified wiring, and scalable control for modern irrigation systems.
