LEIT X 10 to 28 Station Controller

LEIT X 10 to 28 Station Controller

DIG’s LEIT X with 10 to 28 stations supports a permanent solution where there is no available AC power, utilizing only the power of ambient light (solar). The LEIT X is an advanced, ambient light (solar) powered, self-contained water management irrigation controller that provides a cost-effective solution for all type of irrigation applications.


  • Environmentally friendly, using light (solar) as a source of energy
  • Power is provided by photovoltaic module (PVM) and microelectronic management system fueled by ambient light (solar)
  • Operates up to 28 stations plus a master valve or pump start
  • Use with the 1600HE solenoid actuator which mounts on most brand name valves using one of seven valve adapters
  • Programming is easy using a self-guided menu and four durable, sealed buttons
  • Non-volatile memory retains program and controller integrity (excluding time)
  • Bilingual software available in English-Spanish, English-Italian and English-French
  • Lightning protection – the controller is isolated from electrical ground, offering immunity to ground currents from overhead power lines and/or close proximity lightning strikes
  • Simple-to-install wire connector accommodates standard irrigation wire up to 12 gauge
  • Terminal strip can handle 28 hot wire stations, MV/P wire and two common wires
  • Can connect rain, moisture or freeze sensors to an individual valve or to the entire system using an SKIT 8821-4 switch-type sensor (adapter is required)
  • Internal electrical diagnostics circuit activated by the user can detect open wires or short circuits with a message indication in Status Report (deactivated by default)
  • Mounts securely to a rugged galvanized steel-mounting column (2.4″ max OD) using stainless steel lock bolts
  • Vandal-resistant, waterproof enclosure fashioned from super tough material endures extreme hot, cold, wet or dry weather
  • Super-tough Lexan© lens protects the photovoltaic module from moisture, dust, chemicals and impact damage
  • Four-year manufacturer’s warranty

LEIT Controllers Programming

  • Four independent programs with three start times per program allows for mixed irrigation applications
  • Watering durations from 1 minute to 5 hours and 59 minutes per each or all stations to operate with a sprinkler or drip system
  • 365-day calendar with leap year
  • Custom programming with 7-day calendar or intervals from 1-39 days in odd/even or every day rotation
  • Manual Run for repeat testing of individual valves, semi-automatic cycle by station with quick override via manual run, skip to the next valve or run any of the programs
  • Rain delay up to 99 days with auto-restart
  • Monthly water budgeting from 10-200% in 10% increments
  • Status Report provides information on active programs or valves, month deactivation, rain stop, remote or local mode and station progress
  • History Report allows the user to review the controller's operating history for a total watering time of each valve with overall run time total, and manual run time totals. This information is available for the current month and the previous 11 months of the year. The user can also review the current year versus previous year
  • Custom grouping of stations allows the controller to operate more than one group of stations with any number of stations per group (if hydraulic limitations are not exceeded)
  • Month Off option allows override of the controller programs for any month of the year (all months are active by default)

LEIT Controllers Security

  • Programming password eliminates potential user error
  • Password can be changed at any time during program setup activation
  • Standard stainless steel lock secures weather-resistant exterior panel

LEIT Controllers System Components

  • Controller installation required the following components: LEIT X controller, LEIT Key, 1600HE solenoid actuator, valve adapter, or 160HE-XXX inline valve (3/4" to 2") and mounting column
  • Controller installation components (Optional): Skit, switch-type sensor adapter if rain sensor is used, RKIT interface kit if pump or relay is used and stainless steel enclosure to protect the controller
  • 1600HE Solenoid Installation - for LEIT Controllers
