1.2 Coated modules
Coated modules are X20 modules with a protective coating for the electronics component. This coating protects
X20c modules from condensation.
The modules' electronics are fully compatible with the corresponding X20 modules.
Information:
For simplification purposes, only images and module IDs of uncoated modules are used in this data
sheet.
The coating has been certified according to the following standards:
•
Condensation: BMW GS 95011-4, 2x 1 cycle
•
Corrosive gas: EN 60068-2-60, Method 4, exposure 21 days
Contrary to the specifications for X20 system modules without safety certification and despite the tests performed,
X20 safety modules are
NOT suited for applications with corrosive gases (EN 60068-2-60)!
