PointWatch Eclipse® Model PIRECL Carbon Dioxide (CO2) Detector

The PointWatch Eclipse® Model PIRECL Carbon Dioxide (CO2) Detector is a diffusionbased, point-type infrared gas detector that
provides continuous monitoring of CO2 gas concentrations in the range of 0-2%/volume (0-20000 ppm).

All units are powered from 24 Vdc, and are furnished with an onboard “status indication” LED, an internal magnetic calibration switch and an external calibration line for use with the optional PIRTB remote calibration termination box.

The Eclipse CO2 detector is ideal for use in harsh outdoor environments and is certified for use in Class I, Division 1 (CSA),
and Zone 1 (ATEX/IECEx) hazardous areas. It can be used as a stand-alone detector, or as part of a larger facility protection system.

Two basic configurations are available:

• 4-20 mA output with HART communication protocol and RS-485 MODBUS communications.
• 4-20 mA output with HART communication protocol and RS-485 MODBUS communications, with two alarm relays and one fault relay.
• Superior optics protection system.
• No undisclosed failure modes.
• Routine calibration not required.
• Explosion-proof, stainless steel housing with tethered weather protection baffle.
• Integral wiring compartment eliminates need for external junction boxes.
• On-board tri-color LED eliminates need for alarm and fault indication.
• Built-in optional relay package eliminates need for external relay output module.
• Non-interfering HART communication capability.
• Optional hand-held HART communicator enables field configuration and calibration.
• Heated sapphire optics deliver long-lasting, high performance detection capability.
• Immune to damage from exposure to constant background gases or to high gas concentrations.
