I.POWER SOLUTIONS OFFERS FULLY ADJUSTABLE AUSTRALIAN FREQUENCY CURRENT CONVERTER
by Anonymous













The i.Power Solutions Frequency Current Converter operates by converting an input frequency from a Namur proximity sensor located in the hazardous area into a 0/4-20mA current signal. The Namur proximity sensor is connected via a 2 channel I.S zener barrier. However, the unit can operate with or without the IS barrier

The unit boasts fully adjustable settings (that are independent of the module), fault indicators on open and short circuits, and an inbuilt microprocessor ensuring accuracy to .1% as some of its most significant features.

Unlike other comparable products, the component has eight front panel indicators including displays for – Normal, Frequency Setting Error, Short Circuit, Open Circuit and 4 – 20mA fault loop. The 4mA and 20mA currents can be set using the front panel settings (4mA Adj and 20mA Adj respectively).

The user friendly has the following features:
    Front panel rotary setting switch enabling settings to be adjusted without power connection
    Microcontroller based operation enabling accuracy to .1%
    Very linear – the analog output provides a 4 – 20mA signal proportional to the frequency or Input
    Front panel indication lights
    Output 4-20 milliamp loop
    Input or output fault reading
    LED displays for Power On, Sensor Pulsing, Sensor Open, Sensor Short and Process Output
    Directly connects to the Namur sensor

Specifications:
    Input frequency range: 0.5 – 700Hz
    Output current range: 4 – 20mADC
    Pulse frequency maximum: 700Hz
    Pulse frequency minimum: 0.5Hz
    Current output: 4-20mA into 400 ohms
    Power input 24 VDC 1W

The i.Power Solutions Frequency Current Converter is available from i.Power Solutions’ corporate office. For product sales or enquiries, please contact i.Power Solutions on (07) 3893 8222.
