Two or Four Channel Controllers for Fixed Gas Detection Transmitters

Model 9000 Gas Detection Controllers
  • CSA Approved for Class I, Div 2

  • Accepts Two or Four 4-20 mA Inputs

  • Graphic Backlit LCD Display

  • Discrete Alarm Relays

  • Provides 24VDC Power

  • RS-485 Modbus RTU Output

The Model 9000 Dual and Quad Channel Display / Alarm Controllers are designed to provide simultaneous display and alarm functions for up to four monitored variables and is available in two (Dual) or four (Quad) channel versions. A graphic LCD displays monitored data as bar graphs, 30 minute trends and engineering units. Three adjustable alarm levels are provided per channel. Relay outputs allow control of beacons, horns and other alarm events.

Up to 12 watts of 24VDC is available for powering monitors or other devices. An external 50 watt supply available for higher power requirements in the Quad. 4-20mA and Bridge Sensor inputs are offered for interfacing to sensor transmitters that may be long distances from the 9000.

The 9000 is easy to configure and user friendly. Measurement ranges in engineering units, adjustable alarm set-points, optional serial interfaces, and many other features offer flexibility to meet most demanding applications.

An optional RS-485 Modbus slave port allows up to 128 Model 9000’s to be multidropped onto a single data highway for interrogation by another Modbus master. 10-BaseT ethernet is also available utilizing the popular Modbus TCP/IP protocol.
