Model 2250e Boiler Controller
THIS CONTROLLER IS NO LONGER AVAILABLE
THIS PAGE IS FOR INFORMATIONAL PURPOSES ONLY
LonWorks® is the latest in microprocessor technology 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.
This controller can be used in the Continuous Sample, or Sample/Cycle modes to control the boiler water conductivity.
- Cycle/Sample or Continuous sample control of blowdown, configurable in the field.
- Two water meter inputs, conductivity input with 20 ft cable, 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 blowdown, 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.
- Accurate control of boiler conductivity.
- Control results in fuel savings by preventing excessive blowdown
- Prevents carryover due to excessive conductivity
- Two water meter inputs provided for accurate chemical addition.
