E01675 Gasmonitor Plus 24 V 500 W Power Supply 100-260 V AC by Crowcon

Gasmonitor Plus is our flexible microprocessor controlled system designed with a modular approach, so you get exactly what you want.

Used throughout the world, both on and offshore, Gasmonitor Plus provides the cost effective solution to your system requirements. Gasmonitor Plus, the gas and fire control system you can trust.

Simple to use

  • Gasmonitor Plus offers flexibility whilst still providing simple operation. All the day to day functions are accessible via push buttons on the front panel.
  • As well as a rolling display, indicating the channel currently monitored, each channel has a bar graph display. This unique bar graph format is ranged to indicate readings below the first alarm setting, providing an instantaneous representation of the gas concentration on every detector.
  • Common alarm LEDs on the display card and individual alarms on the panel only light when a hazard or fault is detected. This means the whole rack status can be checked at a glance.

Flexible architecture

  • Each channel has three levels of alarm as well as a dedicated analogue output, set as 4-20 mA as standard.
  • Optional relay modules can interface to the panel to provide up to a total of 84 output relays per rack. Sixteen of these relays can be configured/voted from a combination of the three levels of alarm per channel.
  • The RS232 digital interface provides connectivity with PC for configuration, monitoring and datalog upload. Each rack is uniquely addressable, making multi-drop architectures possible. This cuts down on configuration and monitoring cabling.

Ground breaking design

  • Gasmonitor Plus is a microprocessor based expandable control system, which can be multiplied to offer unlimited channels and outputs.
  • Its modular construction provides ultimate customisation capacity with minimal wiring.
  • Gasmonitor Plus has industry standard analogue outputs, and the mechanical design is based on 19” Eurorack. This means that the Gasmonitor Plus will integrate fully with existing rack mounted protection systems on site.
  • The alochrome finish and rack screening plates ensure that the Gasmonitor Plus is impervious to radio frequency interferance.

Easy maintenance

  • Gasmonitor Plus has been designed with easy servicing and maintenance in mind.
  • Each channel is inhibited separately so that plant safety is not compromised during maintenance checks.
  • Routine calibration can be achieved from the front panel. The one man calibration feature reduces the service overhead by half.
  • One universal gas card architecture controls all gas detectors. This reduces the spares holding required for Gasmonitor Plus maintenance. Each control card is fitted with its own dedicated micro-controller so it can function independently in the event of a single point failure.
