HART Communication Port:
Uo = 4.0V Co = 20μF
Io = 100mA Lo = 500μH
IEC Conditions of Certification:
• The field wiring terminal connections are certified for a single wire in size from 0.2 to 2.5 mm2, (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 Gas Detector must be electrically connected to earth ground.
• The gas detector shall be protected against any impact greater than 4 joules.
• The intrinsically safe output on the HART Communicator Port is internally connected to frame.
• The power supply for the detector has to be a Safety Isolating transformer according to e.g. IEC61558. The rating
of the power supply line fuse shall be less than 3.1 A.
• When connecting to a circuit using up to 1% of Co or Lo, then the C or L is limited to the Co and Lo listed above. If
either the C or L is above 1% of Co or Lo, then C or L are each limited to 50% of the Co or Lo listed above.
• Um is restricted to 250 V, prospective short circuit current < 1500 A.
