Rain Bird FD401TURF Field Decoder — Up to 4 Valves - FD401TURF
The Rain Bird FD401TURF field decoder provides reliable in-field control for two‑wire irrigation systems, allowing central controllers to operate up to four valves individually. Designed for buried installation, it reduces wiring and protects electronics from weather and vandalism. Addressing is pre-coded and can be reassigned with Rain Bird's Decoder Programming Unit (DPU) for flexible field management.
Ideal for golf courses, sports fields, and large landscapes, the FD401TURF offers straightforward expansion and dependable operation backed by Rain Bird decoder technology. Install underground to keep controls out of sight and minimize maintenance.
Features
