Model 2450e Reverse Osmosis (RO) System Monitor

1268870_2175Pe_070205

THIS CONTROLLER IS NO LONGER AVAILABLE

THIS PAGE IS FOR INFORMATIONAL PURPOSES ONLY

The Model 2450e uses LonWorks® Technology that is the latest in microprocessor capability, giving the user the highest level of application flexibility.  A large illuminated graphics screen, multiple inputs and very easy setup with easy field upgrades characterize this new technology. Water meters and sensors are purchased separately.

                                               2450e MANUAL

FEATURES

  • Uses 2-electrode or 4-electrode conductivity sensors.
  • Five (5) Count down timers
  • Uses differential pH sensor with ¾ inch MNPT
  • process connection.  pH input can also be configurable for an ORP sensor.
  • Two water meter inputs for Permeate and Concentrate flow rates
  • .RS232 output for remote monitoring, control and data acquisition (-RS2L).
  • Four (4) relays have user-selectable option
  • Includes –RTC card
  • 4-20 mA output for (-35L, select any four, two per –35L card)pH, conductivity, temperature, concentrate flow, permeate flow, percent recovery.
  • Input for CIP lockout.
  • System run timer.

FIVE (5) Count Down Timers

  • Lubrication interval
