It allows an SDS controller to operate conventional 24VAC solenoid valves while retaining the flexibility of the SDS two-wire architecture. Each RelayCube™ adds 24 conventional valve outputs and can be installed anywhere along the two-wire network, making it ideal for retrofit projects, hybrid irrigation systems, and installations where existing multi-wire valve infrastructure needs to be retained. With dedicated 24VAC power, LED status indication, resettable short-circuit protection, and support for mixed DataCoil™ and conventional solenoid operation, the RelayCube™ provides a practical way to expand and modernise existing irrigation systems.\u003c\/p\u003e\n\n\u003ch3\u003eSuitable Applications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eRetrofit irrigation projects using existing 24VAC
