The valve module GH34404412 is part of the Dupline® irrigation concept. It is designed to control 3-wire latching valves. The booster module GH34850000, which generates the 28 V Hi-Line signal, controls, and supplies up to 64 valve modules GH34404412. The GH34404412 features 2 outputs, one for open valve and one for closed valve, and 2 inputs for e.g. flow meter, pulse counting, tamper switch, or status feedback. The module has a built-in charge capacitor for latch/ unlatch coil, a built-in gas arrestor for lightning protection, and a built-in microcontroller for correct coil pulsing and charge monitoring.
