1269226 CONTROLLER KIT 140 w/ 185 &

The Model 140 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. Water meters, sensors

and plumbing assemblies are purchased separately.

 140 with cooling tower Right Exit flowswitch and sensor p/n 1269226

  • Use this Controller for cooling towers.
  • Removable power cord and receptacles for simple conduit installations.
  • Scheduled feed, which can use two relays for biocides or other chemicals.
  • 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.
