- AEx ia IIC T4
- Tamb. –40°C to 80°C
• Non-Incendive for:
- Class I, II, III; Groups A - D, F, G; Divisions 2.
- Class I, Zone 2, Group IIC T4.
- Tamb. –40°C to 80°CEnclosure: Type 4X
• Temp. Code: T4
• Amb. Temp.: –40°C to 80°C
• Enclosure: “Type 4X”
Note 2. Electrical Data
• Intrinsically safe ratings are as follows:
Maximum Input Voltage (Vmax/Ui) = 24 V
Maximum Input Current (Imax/Ii) = 150 mA
Maximum Input Power (Pmax/Pi) = 0.85 W
• Installation Requirements
Uo ≤ Ui, Io ≤ Ii, Po ≤ Pi,
Co ≥ Ci + Ccable, Lo ≥ Li + Lcable
Voc ≤ Vmax, Isc ≤ Imax,
Ca ≥ Ci + Ccable, La ≥ Li + Lcable
Uo, Io, Po, Co, Lo, Voc, Isc, Ca and La are parameters of barrier.
Note 3. Wiring
All wiring shall comply with Canadian Electrical Code Part I and Local Electrical Codes.
• For an ambient temperature ≥ 70°C, heat resistant cables shall be used with a
rating of at least 20°C above the ambient temperature.
• In hazardous location, wiring shall be in conduit.
WARNING: A SEAL SHALL BE INSTALLED WITHIN 50 cm OF THE
ENCLOSURE.
When installed in Division 2,“FACTORY SEALED, CONDUIT SEAL NOT
REQUIRED”.
• In hazardous location, wiring shall be in conduit.
WARNING: A SEAL SHALL BE INSTALLED WITHIN 50 cm OF THE
ENCLOSURE.
UN SCELLEMENT DOIT ÊTRE INSTALLÉ À MOINS DE 50 cm DU
BOÎTIER.
• When installed in Division 2,“FACTORY SEALED, CONDUIT SEAL NOT
REQUIRED”.
Une fois installé dans la Division 2, «scellés en usine, CONDUIT SEAL PAS
NÉCESSAIRE".
Note 4. Installation
• All wiring shall comply with local installation requirements.
• In any safety barreir used output current must be limited by a resistor 'R' such
that Io=Uo/R or Isc=Voc/R.
• The safety barrier must be CSA certified.
• Input voltage of the safety barrier must be less than 250 Vrms/Vdc.
