• Base module (BC, HB, etc.)

• Supply module

The left and right end plates are included in the delivery.

• Bus base

2 Coated modules

Coated modules are X20 modules with a protective coating for the electronics component. This coating protects

X20c modules from condensation and corrosive gases.

The modules' electronics are fully compatible with the corresponding X20 modules.

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

2.1 -40°C starting temperature

The starting temperature describes the minimum permissible ambient temperature when the power is switched

off at the time the coated module is switched on. This is permitted to be as low as -40°C. During operation, the

conditions as specified in the technical data continue to apply.

Information:

It is important to absolutely ensure that there is no forced cooling by air currents in a closed control

cabinet, for example using a fan or ventilation slots.
