GE Oil and Gas Chatterbox-e Pulse Isolation Unit with Volt-free contact closure

Product Details

The Chatterbox-e unit provides the necessary safety isolation between equipment generating pulses in the hazardous area and non-intrinsically safe equipment located in the safe area. Opto-isolators provide four isolated volt-free contacts from low frequency pulses generated by Gas Meters or Volume Correctors installed in the hazardous area.

Chatterbox-e operates from a self contained power supply lasting in excess of 10 years and is therefore suitable for installation in remote and difficult environments without the need for an external power supply. During 10 years of operation the Chatterbox-e will save hours of labour on site.

The unit comprises of four independent circuits that transform high impedance pulses, or volt-free contact closures, into isolated volt-free contact closures. One input can be connected to up to 4 isolated output circuits by using internal switches.

No Corrector or Meter setting required; as soon as the Chatterbox-e receives a pulse, a 220ms isolated outlet pulse is generated.
