The Irritrol TW-D-2 is a two-wire decoder designed for 24 VAC irrigation systems to control two valves from a single address point. It simplifies wiring and reduces installation time by pairing with compatible two-wire controllers and Rain Master Eagle Plus systems. Ideal for retrofit or new installations where minimizing trenching and wire runs is important.

  • Dual-valve operation: controls two separate irrigation valves from a single decoder address, reducing controller station requirements.
  • 24 VAC operation: accepts standard 24 VAC decoder-bus power and integrates with two-wire control systems.
  • Compact, field-serviceable design: installs in valve boxes or junction enclosures for convenient access during maintenance.
  • Wire-saver benefits: reduces the need for long multi-conductor cable runs and simplifies large-site wiring layouts.
  • Includes documentation: user guide, sell sheet, and quick reference provide wiring diagrams, addressing, and setup instructions.

Designed for professional installers and landscape contractors, the TW-D-2 helps simplify paired-valve control while cutting installation labor. Verify compatibility with your controller before installation and consult the supplied documents for addressing and safety information. For technical questions, refer to the manufacturer's user guide or contact support.
