The Series 330 is a compact, programmable relay control capable of converting the signal from a Data Industrial flow sensor into a flow switch.

With an onboard microcontroller and digital circuitry, the Model 330 is programmed from a Windows® based computer program. This eliminates the need to set dip switches or potentiometers and produces precise, accurate and drift free control of the relay outputs. In addition to accepting the Data Industrial square wave signal, the Model 330 can accept other pulse and sine wave inputs.

The compact cast epoxy body measures 1.75" (44mm) x 2.75" (70mm) x 1" (25mm) and can easily be mounted to panels, DIN rails or enclosures. With multiple inputs, ease of use and a variety of enclosures, the Model 330 is a powerful, competitive priced relay control.

- Flow / no flow indicator
- High Flow / Low Flow alarm monitor
- Booster pump control
- Multiple pump staging
- Leak control

Selectable Alarm Type - The Model 330 may be programmed as a high flow alarm where the relays are energized when the flow rate exceeds the set point, or as a low flow alarm where the reverse is true and the relays energize when the flow rate falls below the set point.

Programmable Set & Release Points - The set point, the flow rate where the relays are energized, is programmed independently from the release point, the flow rate where they are de-energized. This adjustable deadband prevents relay chatter and control cycling.

Programmable Time Delays - This feature provides a time delay between crossing the set or release point and energizing or de-energizing the relay. This feature allows surges in the flow to dampen out before the control circuit reacts.

Latch Feature - The latch maintains the relays in the energized state even when the alarm condition has been satisfied, until manually reset.

Remote Reset - This allows all the control parameters of the Model 330 to be reset by an external signal.
