TWICE™ - 2-wire

Rain Master now offers yet another "Intelligent" option...

Unlike other two-wire systems, Rain Master’s TWICE protocol provides a two-way communication link between the controller, decoders and valves.  This provides the means for testing and diagnostic capabilities within the two-wire path.  The simplicity of the two-wire field installation, coupled with the enhanced capability of Rain Master’s ‘E’ series controllers, sets a new precedent for "Two-Wire" control within the irrigation industry.

The TWICE Two Wire Interface Module; TWICE is compatible with the Sentar II and Eagle / Eagle-i controllers.  Two-way communication Decoders insure system integrity between the TWICE module and irrigation valves.
