The certification of this equipment relies upon the following materials used in its
construction:
—
—
—
•
If the equipment is likely to come into contact with aggressive substances, then it is the
operator's responsibility to take suitable precautions to prevent it from being adversely
affected, thus ensuring that the type of protection provided by the equipment is not
compromised.

•
The output of the optical radiation source with respect to explosion protection meets
Exception 3 from the scope of UL 60079-28.
5.4.1
Intrinsically safe (I.S.) outputs
Intrinsically safe outputs through the I.S. ports have the following parameters:

Po
111.5 mW
Ci

Co
22 µF
Lo
7.5 mH
Note
Co @ 6.6 V is 22 µF, as per Table A.2 of IEC 60079-11:2011. Lo is calculated based on 1.5
times current for IIC, 40 µJ using E = 0.5 *(LI)

Enclosure: 316L stainless steel
Windows: sapphire glass
Seals: EPDM
Aggressive substances: For example, acidic liquids or gases that may attack metal or
solvents that may affect polymeric materials.
Suitable precautions: For example, regular checks as part of routine inspections or
establishing from the material's data sheets that it is resistant to specific chemicals.
