ORP Controllers Model 2330P from Lakewood Instruments

Model 2330P ORP Controllers

LONWORKS^* Technology is the latest in microprocessor capability that gives the user the highest level of application flexibility.

A large illuminated graphics screen, multiple inputs and very easy setup with easy field upgrade characterize this new technology.

The unit does not include plumbing or a sensor. For use with process-type ORP sensors (order separately).

• Differential ORP sensor input with diagnostics indicate fouled reference or open PT band.
• Input for flowswitch lockout.
• Two water meter inputs, MTR1 and MTR2.
• Four user-selectable relay options (four additional with NRLY):

  Feed by setpoint, direct or reverse;
  Water meter actuated feed. MTR1, MTR2 or sum;
  Feed by percentage of time;
  Feed by schedule (-RTC Option);
  General alarm contact.

• Three security levels:
