FD-TURF Field Decoders
for SiteControl and MDC Decoder Systems

Rain Bird Field Decoders provide easy, cost-effective installation and expansion for SiteControl Decoder or MDC Decoder Central Control Systems. Decoders are installed out of sight to help protect them from the elements and vandalism. Select different decoders to operate one, two, four, or six valves/solenoids. Five different decoders let you choose the amount of control you need.
