The 1KGT033300R1002 is the ABB ordering reference for the 520BOD01 Binary Output Module, a hardware component used to transmit digital output commands from an automation controller to external equipment.
Within an ABB automation station, this module performs the final switching interface between the control system and field-operated devices. It receives command signals from the controller and delivers discrete output signals to connected equipment such as relays, contactors, indicator lamps, or interface circuits.
Because binary output modules are available in multiple hardware variants, the complete ABB article number is the primary reference for lifecycle replacement and inventory management.

Operational Position
Unlike processors that execute control programs or communication modules that transfer network data, the 520BOD01 is dedicated to issuing discrete control signals.
A simplified control sequence is shown below.
| Control Stage | Hardware Role |
|---|---|
| Control application | Generates switching command |
| Processor | Executes logic |
| 520BOD01 | Converts command into binary output |
| External device | Receives switching signal |
| Industrial process | Performs required action |
The module serves as the output interface that transfers controller decisions to connected field equipment.
Common Controlled Devices
Typical connected equipment includes various electrically operated components requiring ON/OFF control.
| Connected Equipment | Typical Function |
|---|---|
| Interface relays | Switching auxiliary circuits |
| Magnetic contactors | Motor circuit control |
| Indicator lamps | Operating status indication |
| Alarm devices | Audible or visual notification |
| Solenoid valves | Process actuation |
Actual connected loads depend on the control system configuration.

| Functional Role | Digital output interface |
| Mounting Method | System rack installation |
| Signal Category | Binary output |
| Controller Compatibility | ABB automation platform |
| Module Design | Plug-in construction |
The 520BOD01 is intended for use within compatible ABB controller hardware rather than as a standalone switching device.
Industrial users often keep this module available for:
- Scheduled controller maintenance
- Automation rack spare inventory
- Production equipment refurbishment
- Failed output module replacement
- Expansion of installed ABB control systems
The article number recorded in plant documentation should always match the replacement component.

Ordering Verification
Before selecting a replacement module, maintenance personnel generally verify the following information.
| Verification Item | Match Required |
|---|---|
| ABB Article Number | 1KGT033300R1002 |
| Module Identification | 520BOD01 |
| I/O Category | Binary Output |
| Installed Automation Platform | Existing ABB system |
| Hardware Revision | Compatible revision where applicable |
Using only the module appearance is not recommended because multiple ABB I/O modules share similar mechanical dimensions.
