HART Communication Port:
Uo = 4.0V
Co = 20μF
Io = 100mA
Lo = 500μH
IeC Conditions of Certification (general):
• The Infrared Gas Detector model PIRECL shall be installed in places where there is a low risk of mechanical damage.
• The field wiring terminal connections are certified for a single wire in size from 0.2 to 2.5 mm
2
, (or two conductors with
same cross section 0.2 to 0.75 mm
2
).The screws must be tightened down with a torque 0.4 to 0.5 Nm.
• The metal housing of the model PIRECL Infrared Carbon Dioxide Gas Detector must be electrically connected to earth
ground.
• The Infrared Gas Detector model PIRECL has an ambient temperature rating of –55°C to +75 °C.
• Alarm output latching requirement: High alarm outputs must be configured as latching, either as part of the alarm
operation of the gas detector itself (in stand-alone applications), or as a function of the “high alarm” indication within the
controller that is directly connected to the gas detector (for remote applications).
Special conditions for safe use for the [ib] harT communication port only:
• The PointWatch Carbon Dioxide Infrared Gas Detector model PIRECL shall be powered from a Safety Isolating Transformer
according to IEC60742 or IEC61588.
• The maximum cable distance between the HART Communicator and the PIRECL Infrared Carbon Dioxide Gas Detector
is 610 meters.
