Signal SD-WF Plug-In WiFi Module for SDS Two-Wire Irrigation Controllers – Local Network Connection

The Signal SD-WF Plug-In WiFi Module is a compact communications accessory designed to connect Signal SDS Series Two-Wire Irrigation Controllers to an existing local wireless network. Installed directly through the controller’s serial interface, the SD-WF enables compatible SDS controllers to communicate with SignalCloud™ for browser-based central control and with the SDS-LINK mobile app for remote irrigation management. It is a practical, low-cost connectivity option for sites with strong and reliable 2.4 GHz WiFi coverage, providing remote programming, flow alerts, and live system monitoring without requiring a SIM card or mobile data plan. Suitable Applications Signal SDS irrigation systems with reliable local WiFi coverage Commercial landscape irrigation systems Agricultural and horticultural irrigation sites Sports fields and turf irrigation installations Schools, campuses, and managed estates Sites requiring SignalCloud™ remote access without a mobile data plan Indoor or accessible controller installations with strong wireless signal Remote programming and irrigation monitoring through SDS-LINK Systems requiring flow alerts and live controller status reporting Key Specifications Product Name Signal SD-WF Plug-In WiFi Module Model SD-WF Product Type Plug-In WiFi Communications Module for SDS Irrigation Controllers Connectivity Local 2.4 GHz WiFi Network Controller Interface Serial Port Connection Compatible Controllers Signal SDS-50 and SDS-100 Cloud Platform SignalCloud™ Mobile App SDS-LINK for iOS and Android Remote Functions Programming, Monitoring, Flow Alerts, and Live System Status Power Supply Powered through the SDS Controller Interface SIM Card Required No Mobile Data Plan Required No WiFi Requirement Strong and Reliable Local 2.4 GHz Wireless Signal Suitable Enclosure Type Non-Metallic or Locations Where WiFi Signal is Not Shielded Metal Cabinet Compatibility Not Recommended Due to Wireless Signal Interference Alternative Connectivity for Shielded Enclosures Signal SD-MD 4G Modem or Compatible Ethernet Kit Features Simple plug-in installation through the SDS controller’s serial port Connects compatible SDS controllers to an existing 2.4 GHz WiFi network Enables access to SignalCloud™ for web-based central irrigation management Works with the SDS-LINK mobile app on compatible iOS and Android devices Allows remote irrigation programming and schedule adjustments Supports live controller and system monitoring Allows compatible flow alerts and system notifications to be viewed remotely Uses the site’s existing WiFi network, eliminating the need for a SIM card No separate mobile data subscription is required Powered directly through the SDS controller interface Designed for locations with strong and stable wireless coverage Provides a cost-effective communications option for connected SDS installations Installation Considerations A strong and reliable 2.4 GHz WiFi signal should be available at the controller location before installation. The SD-WF should not be installed where a metal electrical enclosure significantly blocks or weakens the wireless signal. For controllers installed inside metal cabinets or other shielded environments, a Signal SD-MD 4G modem or compatible Ethernet connection should be considered instead. Local network availability, wireless signal strength, and internet access should be confirmed before commissioning SignalCloud™ remote services.
