8-Channel Programmable Controller for Oxygen, Carbon Dioxide & Combustible Gas Detectors

8-Channel Programmable Controller for Oxygen, Carbon Dioxide & Combustible Gas Detectors

Item #: 99196


Product Summary

The PureAire 8-Channel Controller is designed to provide simple analog control or full-featured digital control of toxic, LEL, and oxygen deficiency monitors. The controller remotely powers and operates up to 8 monitors up to 100 feet from the controller. Capable of accepting any two or three-wire gas detector, it features two user-adjustable common alarm relays which will, in the event of a gas leak, or a fault from one of the monitors, alert personnel.

The multi-channel controller incorporates various modes of operation for taking channels offline individually for performing calibration or sensor maintenance. Each channel can be individually designated with PPM, PPB, or %. The LCD screen displays the readings from all 8 channels simultaneously, and the trends from each channel may be viewed in graph form over a period of time.

  • Designed to control and power 8 monitors
  • Connects any 2-wire or 3-wire gas sensors
  • Digital and graphic LCD gas concentration
  • RS-485/Modbus RTU output
  • Built-in power supply
  • NEMA 4X IP66 Water-Resistant Enclosure
  • Two-year warranty

The PureAire Multi-channel Controller connects 2-wire or 3-wire to oxygen monitors, analyzers, or gas detectors. The built-in power supply allows the multi-channel controller to power the monitors located up to 100 feet away. The 2 adjustable relays allow you to create desired audible warnings notifying workers.

PureAire’s Controller comes pre-wired for easy installation. Simply connect the gas monitors to the Controller, and connect the built-in power supply to the main power source.

The 8-channel controller allows users to take channels offline individually for easy calibration or sensor maintenance. While one channel is offline, the other systems will continue to operate normally.

The multi-channel controller allows you to set specifications for each gas sensor for quick differentiation. The LCD graphical display shows current data across all connected channels or trend data over a selected time period. You can manage controller display data in percentage, parts-per-million (PPM), or parts-per-billion (PPB). An RS-485 Modbus communication interface is available upon request.
