K-Rain - 3322 - Pro Ex3 2-Wire Module

2-Wire Decoder Module for Pro EX3 Modular Controller (3322) Description The K-Rain PRO-EX3 2-Wire Module (3322) enables advanced decoder-based irrigation control by converting the PRO-EX3 controller into a hybrid 2-wire system. Designed for maximum flexibility, this module allows irrigation systems to operate over a single 2-wire path—dramatically reducing wiring requirements while expanding system capacity. Installed directly into the PRO-EX3 controller, the 2-wire module communicates with field decoders to control individual valves across large or complex landscapes. This approach eliminates the need for multiple wire runs, making it ideal for new installations, retrofits, and sites with challenging trenching conditions. The PRO-EX3 supports both conventional modular wiring and 2-wire technology simultaneously, allowing users to build hybrid systems that scale efficiently over time. The 2-wire module can operate independently or alongside standard station modules, providing unmatched design flexibility. With simple installation and seamless integration, the 3322 module is a powerful solution for contractors and property managers looking to expand irrigation systems while minimizing labor and material costs.
