X20AO2437 B&R

For a description of the various operating modes, see section "Additional information - Diagnostic LEDs" of the

X20 system user's manual.

The module is equipped with 2 current outputs with 16-bit digital converter resolution. The 2 channels are electrically

isolated from each other. The user can select between the 3 output ranges 4 to 20 mA, 0 to 20 mA and 0 to 24 mA.

• 2 analog current outputs

• Electrically isolated analog channels

• 16-bit digital converter resolution

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

1) Based on the current output value.

2) Based on the respective output range

3) Load change from 1 Ω → 600 Ω, resistive

4) Based on the entire output range.
