Dresser Chatterbox-e Isolation Unit

The Chatterbox-e is an Opto-Isolation Unit that provides necessary Volt-Free isolation between Meters generating pulsed outputs in a hazardous area and equipment that is not intrinsically safe located outside of the hazardous area. A long life battery provides reliable usage for up to 10 years after installation with no need for external power supply at all. This allows the Chatterbox to be installed almost anywhere. The enclosure is IP66 rated as it is a weatherproof aluminium housing.

The Chatterbox has three cable glands as standard which are normally used as one gland to suit the pulsed inputs and then two glands for outputs from the unit. The Chatterbox has four channels for accepting pulses in and sending pulses out. Using internal switches, pulses can be split to provide dual output.
