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
