THIS CONTROLLER IS NO LONGER AVAILABLE

THIS PAGE IS FOR INFORMATIONAL PURPOSES ONLY

LonWorks® Technology is the latest in microprocessor capability that gives the user the highest level of application flexibility.  A large graphic screen, multiple inputs and very easy setup with easy field upgrade characterize this new technology.

 

Removable power cord and plug outlets make installation easy.  For use with process-type pH sensors; ordered separately.

 

 

 

2350Pe MANUAL


 

FEATURES

  • Two water meter inputs, pH sensor input, flow switch input, four relay outputs, and Power On/Off switch in a NEMA 4X enclosure are all standard features.
  • Removable power cord and receptacles for simple conduit installations.
  • Includes four relays for chemical feed, and alarms; expandable up to 12 relay outputs.
  • Includes three security levels to prevent unauthorized programming access.
  • Includes two languages; English/Spanish are standard.
  • Heavy-duty stainless steel domed numeric keypad and large illuminated graphical display allow for quick and easy programming.  Steel domed switches improve the tactile sensing and life expectancy of the keypad.

 


 

BENEFITS

  • Easy to program with the Lakewood plain English, intuitive, and user friendly menu interface.
  • Expandable in the field with the use of the Nodes for additional inputs, such as additional sensor inputs or additional outputs such as relays, 4-20 mA, LonWorks, and remote communications.
  • Able to feed chemicals by multiple feed schemes including by feed schedule, setpoint control, percent of blowdown, percent of time, and by water meter.
  • Able to bleed based on setpoint or by water meter.
  • Includes sensor diagnostics and alarms.
