Protection against humidity & corrosive environments
06 August 2014
With the X20c series, B&R claims to set new standards for protection against harsh environmental conditions. The 'coated' variants of the compact controller and I/O modules are protected against condensation and corrosive gases by a special coating on the electronics module.
The coating on the electronics module protects the components and circuit board from the effects of condensation and corrosive gases. Effectiveness of protection against condensation is checked using the test specified in BMW GS 95011-4, and protection against corrosive gases using the 4-part corrosive gas tests specified in EN 60068-2-6, test method 4.
The X20 modules with coated circuit boards offer the same functionality as existing models. Their introduction represents the third time that B&R has extended the range of applications in which the X20 system can be used. The operating temperature range for all X20 modules was recently expanded to -25°C to +60°C. The X20 System has also received certification for maritime applications from Germanischer Lloyd (GL).
