New Dresser Chatterbox-e Isolation Unit

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 labor 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.

  • 10 Year battery life from standard cells, two 1/2 AA lithium.
  • 4 Channels as standard
  • Channel selections via switches
  • Two output connectors, as standard, allows connections to two independent systems
  • Certified Intrinsically Safe
  • IP66 Housing (outer box)
  • Weatherproof cast aluminum housing, rated to NEMA 4X, offers flexibility of installation
  • Compliance to Article 500 of the National Electrical Code® ANSI/NFPA-70 (NEC®)
  • Opto isolation increases reliability and reduces power consumption
  • Simple mechanical and electrical installation
  • Single or multiple outputs from single input
  • No Corrector or Meter setting required; as soon as the Chatterbox-e receives a pulse, a 220ms isolated outlet pulse is generated

INPUTS
Each input is designed to interface with the current 'sinking' pulse outputs of the ROOTS®Micro Corrector to a maximum of 7.4V. The input will also interface directly with a volt-free contact closure, i.e., directly to a gas meter. Contact debouncing as standard.

OUTPUTS
Each output is a 220ms pulse, current sinking output capable of accepting up to 20V, 130mA.

ENCLOSURE
Weatherproof aluminum enclosure NEMA 4X rated. Size: 6.4” width, 4.8” height x 2.5” depth.

INTRINSIC SAFETY
BASEEFA 05 ATEX 0429 II(1) G [EEx ia] IIC. The Chatterbox-e must be installed in the safe area and is suitable for connection to equip-ment in hazardous areas Class 1 Division 1, Groups C and D.

POWER SUPPLY
Two 1/2AA Lithium cells giving an estimated life in excess of 10 years based on all four channels operating and an input frequency of <1 Hz from a volume converter.

Standard delivery - most items

A parcel courier or Royal Mail will deliver your item/s between the hours 08.00 - 18.30 usually within 2-4 days after your item has been dispatched (unless you have selected an express delivery option).

Over sized items

A parcel courier or pallet delivery firm will deliver your item between the hours 08.00 - 18.30 usually 2-4 days after your item has been dispatched. All large item deliveries are 'kerb side' only which means the courier will not be able to take items into your delivery address. The receiver must arrange for larger items to be taken from the driver - heavy items will need 2 persons.

Tracking

After checkout you will receive a tracking number, you can track your parcel anytime after 19.00 on this day. Please note - Delivery times to some areas of Scotland, the Scottish Highlands, Islands and outside the UK mainland, excluding Ireland can vary and items can take up to 4-5 working days to reach their destination after dispatch.
