Model 2875e Conductivity Controller (8 Relay)

1269020 2875e-BASIC-MP 

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

Power cord, plug outlets and detached plumbing make installation easy.  There is plenty of protected room inside the enclosure for electrician wiring.

Shown with optional mounting plate

 

                   2875e MANUAL


FEATURES

  • Two water meter inputs, conductivity inputs with sensor with 20 ft cable, flow switch input, eight relay outputs (seven with drop cords), and Power On/Off switch are all standard features.
  • Removable power cord and receptacles for simple conduit installations.
  • Includes seven relays for bleed, 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 chiller loop monitor and cycles of concentration based on incoming makeup water, or additional outputs such as 4-20 mA and remote communications.
  • Able to feed chemicals by multiple feed schemes including biocide addition, setpoint control, percent of blowdown, percent of time, and by water meter.
