Boiler Conductivity Controller Model 150

The Model 150 uses the latest in microprocessor capability, giving the user a high level of application flexibility. Multiple inputs and very easy setup characterize this new technology.

This controller can be used in the Continuous Sample, Sample/Cycle, or Sample/Hold modes to control the boiler water conductivity.

Features
  • Use this Controller for conductivity control of boilers. It can be used for Continuous Sample, Sample/Cycle, or Sample/Hold control of boiler conductivity.
  • Removable power cord and receptacles for simple conduit installations.
  • One (1) water meter input, conductivity input, flow switch input, and 4-20 mA output are all standard features.
  • Designed with a single circuit board for better reliability and lower cost.
  • Large open shallow enclosure for easy wiring.
  • The enclosure is rated NEMA 4X.
  • Power selector switch for 115 or 230 vac operation.
  • Heavy-duty stainless steel domed numeric keypad and illuminated graphical display allow for quick and easy programming. Steel domed switches improve the tactile sensing and life expectancy of the keypad.
  • LED indicators for power, alarm and relay status.
  • The display is lit by two LEDs when any key is pressed.
    • Easy to program, the Model 150 Controller uses an intuitive menu and a numeric keypad for programming.
    • No add-on options. Flow switch input, 4-20mA output, and three boiler conductivity control methods; Continuous Sample, Sample/Cycle, and Sample/Hold are standard.
    • Single circuit board design improves reliability.
    • Multiple methods of chemical feed for application flexibility.
