Use BX-04AD-2B.dwg for the identified module. The voltage-input function distinguishes it from the BX-04AD-1 current-input module and the BX-04AD-3 universal-input module. Check the matching terminal block, wiring and supported signal configuration separately.


## In plain English

### What is this AutomationDirect resource?

The BX-04AD-2B is a BRX analogue voltage-input expansion module. It brings selected field voltage signals into the controller’s measurement system.

### A simple example

A process panel can bring a compatible voltage-output instrument to this module while using its physical drawing to coordinate the panel space and terminal access.

### What the drawings help you do

Use BX-04AD-2B.dwg for the identified module. The voltage-input function distinguishes it from the BX-04AD-1 current-input module and the BX-04AD-3 universal-input module. Check the matching terminal block, wiring and supported signal configuration separately.

### Before using this reference

- Match the complete 2B model code.
- Confirm the required terminal block and signal types.
- Check the input configuration and voltage-signal reference.

### Can a current-loop signal be assumed compatible with this voltage-input variant?

No. Signal compatibility must follow the selected module’s instructions and any intentionally designed interface. Do not infer it from the shared BRX housing.

### Terms

- Geometry: The physical shape represented by the model or drawing.
- Configuration: The exact equipment version and options selected for the installation.
- Revision: The recorded version of the file or document.
