The Model 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.
