Signal SDS-50 Two-Wire Irrigation Controller with PumpNode™ & SignalCloud™ Connectivity – 48 Station

The Signal SDS-50 Two-Wire Irrigation Controller is an Australian-designed and manufactured commercial irrigation control system built for demanding landscape and agricultural applications. Supporting up to 48 stations, eight independent programs, and operation of up to four valves simultaneously, the SDS-50 uses Signal’s patented DataCoil™ technology to integrate decoder functionality directly into compatible valve coils. This eliminates the need for separate field decoders and simplifies installation across a twisted-pair two-wire path. With advanced sensor integration, flow monitoring, PumpNode™ pump control, fertigation support, SignalCloud™ remote management, and mobile control through the SDS-LINK app, the SDS-50 provides a flexible and highly serviceable solution for professional irrigation systems. Suitable Applications Commercial landscape irrigation systems Golf courses and recreational facilities Municipal parks and public open spaces Agricultural and farm irrigation systems Commercial estates and large landscaped properties Sports fields and turf irrigation systems Two-wire irrigation installations requiring simplified field wiring Sites requiring moisture, flow, or frost sensor integration Irrigation systems requiring pump, booster pump, or fertigation control Remote-managed irrigation sites using cloud and mobile connectivity Key Specifications Product Name Signal SDS-50 Two-Wire Irrigation Controller with PumpNode™ & SignalCloud™ Connectivity Model SDS-50 Country of Design & Manufacture Australia Product Type Commercial Two-Wire Irrigation Controller Station Capacity Up to 48 Stations Simultaneous Valve Operation Up to 4 Valves Simultaneously, Including Master Valve Two-Wire Technology Signal DataCoil™ and DataValve™ System Separate Field Decoders Required No, Decoder Functionality is Integrated into Compatible DataCoil™ Valve Coils Programs 8 Independent Programs Start Times Up to 4 Start Times per Program Run Modes Time (Hr:Min:Sec), Volume (Litres), or Precipitation (mm) Calendar Types 14-Day, Odd/Even, and Cyclic Field DataNodes™ Up to 12 Programmable DataNodes™ on the Two-Wire Path Direct Sensor Inputs 7 Inputs on the Controller Moisture Sensor Capacity Up to 8 Moisture Sensors, 1 per Program Water Meter Support Up to 8 Water Meters Frost Sensor Capacity Up to 2 Frost Sensor Programs Flow Monitoring Real-Time Flow Deviation Detection with Alerts and Automatic Shutdown Options HydroSector™ Matched Precipitation and Flow-Zone Programming Primary Pump Control PumpNode™ Included Additional Pump Control Supports Auxiliary Chemical Pump and Booster Pump Assignment by Program Fertigation Support Supported Communication Two-Way Communication Approximately Every 3 Seconds Between Compatible System Devices Remote Connectivity Wi-Fi, Ethernet, 3G/4G, or Radio Modem Cloud Platform SignalCloud™ Web Portal Mobile App SDS-LINK for iOS and Android SignalCloud Device Support PC, Mac, Smartphone, and Tablet Construction Modular Plug-In Board Architecture Dimensions (H × W × D) 179 × 199 × 106 mm Features Controls up to 48 irrigation stations from a single two-wire controller Operates up to four compatible valves simultaneously, including the master valve Uses patented DataCoil™ technology with decoder functionality integrated directly into compatible valve coils Eliminates the need for separate conventional field decoders Two-wire architecture helps reduce field cabling, trenching, splice points, and installation complexity Eight independent programs provide flexible irrigation management for multiple site areas Programs can operate by elapsed time, measured water volume, or precipitation depth HydroSector™ matched precipitation programming allows compatible irrigation areas to be organised according to hydraulic and precipitation requirements Supports up to 12 programmable field DataNodes™ across the two-wire path Seven direct controller sensor inputs allow additional custom monitoring applications Supports up to eight moisture sensors for moisture-responsive irrigation management Supports up to eight water meters for flow and usage monitoring Supports frost sensor logic across two irrigation programs Real-time flow deviation monitoring can detect abnormal system operation and generate alert notifications Automatic shutdown protocols can help protect the irrigation system when configured flow faults are detected PumpNode™ is included for primary pump activation Supports auxiliary chemical pumps and booster pumps for fertigation and advanced hydraulic applications Two-way communications provide frequent status exchange between compatible field devices and the controller SignalCloud™ enables remote system programming and monitoring through compatible internet connections SDS-LINK mobile app provides site access and irrigation control from compatible smartphones and tablets Modular plug-in circuit boards simplify controller servicing and component replacement Compact enclosure allows installation where control-space availability is limited What's Included Signal SDS-50 Two-Wire Irrigation Controller Plug-In Power Supply Lightning Protection Module PumpNode™ Two-Wire Device Programming Leads Documentation & Downloads Signal SDS Series Instruction Manual Download
