Frequency current convertor goes underground

i.Power Solutions is now offering a competitive choice in current convertor technology with the development of a new frequency current convertor for underground applications.

i.Power Solutions is now offering a competitive choice in current convertor technology with the development of a new frequency current convertor for underground applications.

Developed and manufactured by Bramco Electronics through a co-operative association with i.Power Solutions, the device has been specifically designed for speed monitoring of conveyor pulleys or any other high frequency rotating device.

The i.Power Solutions frequency current convertor 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 two-channel IS 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 0.1% 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 4 and 20mA currents can be set using the front panel.

The user friendly unit has the following features: a front panel rotary setting switch enabling settings to be adjusted without power connection; microcontroller based operation enabling accuracy to 0.1%; a highly linear analogue output that provides a 4-20mA signal proportional to the frequency or input; front panel indication lights; input or output fault reading; and LED displays for power on, sensor pulsing, sensor open, sensor short and process output.
