Description
🔹 Product Overview
The BOSCH 044340-2067 is an industrial CNC control board associated with Bosch NC/PLC control systems. The board is identified by several reference numbers, including 044339-301401 and 048499-112401, and is also associated in industrial spare-parts listings with Bosch part number 1070048499-112.
This type of Bosch control card is intended for use within legacy CNC, NC and PLC-based industrial control architectures. It can be particularly useful when maintaining older machine tools where replacing the complete controller is impractical and an exact board-level spare is required.
Because Bosch produced multiple visually similar control boards with different hardware revisions and functions, the board markings, connector arrangement, revision information and system configuration should be checked carefully before installation.

🏭 CNC & Industrial Control Applications
The 044340-2067 control card can be considered for older Bosch CNC/NC machine architectures where the controller is divided into dedicated processor, PLC, interface and control-board functions.
Typical maintenance applications may include:
- CNC machine tools
- NC machine controllers
- Industrial PLC control cabinets
- Machine-tool automation systems
- Servo-controlled production equipment
- Legacy Bosch numerical-control systems
- Controller repair and board-level replacement
For an existing machine, the replacement board should be matched against the original hardware before commissioning. Particular attention should be given to connector locations, board revision, firmware compatibility and the exact Bosch controller configuration.
🔌 System Integration
Before replacing the board, record the existing controller configuration and identify all connected interfaces.
Recommended checks include:
- Record the complete Bosch part number and all secondary board markings.
- Photograph connector positions and cable routing before removal.
- Confirm that the replacement board has the same connector configuration.
- Compare revision and hardware identification markings.
- Check the machine PLC/NC configuration for compatibility.
- Verify memory, parameter and program requirements where applicable.
- Inspect the backplane and connector contacts for oxidation or mechanical damage.
- Perform a controlled power-up after installation.
- Check CNC/PLC diagnostics for hardware or communication alarms.
- Run machine functions gradually before returning the equipment to production.
🛠️ Installation & Maintenance
Handle the board using appropriate ESD precautions. Disconnect system power before removing or installing the card and avoid touching exposed PCB contacts.
For long-term storage, keep the board in an antistatic package in a clean, dry environment. Avoid excessive humidity, dust, vibration and temperature fluctuations.
When replacing an existing board, retain the removed unit until the replacement has completed functional testing. This provides a useful reference for comparing jumpers, connectors, revisions and board markings.
🔍 Troubleshooting
Board is not recognized after installation:
Check seating, backplane contacts, connector orientation and the exact board identification.
CNC or PLC reports a hardware fault:
Compare the replacement board revision with the original and check whether the machine configuration expects a specific hardware version.
Communication or I/O problems occur:
Inspect interface connectors, cable routing and associated controller modules before assuming the board itself is defective.
Machine parameters are abnormal:
Verify the control-system configuration and machine parameters. Do not overwrite the original configuration until a verified backup is available.
Intermittent operation:
Inspect connectors, solder joints, contamination, oxidation and power-supply conditions.
✅ First-Operation Checklist
Before putting the machine back into service:
- Confirm 044340-2067 identification.
- Confirm 044339-301401 and 048499-112401 markings where applicable.
- Compare the replacement PCB with the original board.
- Verify connector and backplane compatibility.
- Check for visible PCB damage or corrosion.
- Confirm the control cabinet power supply.
- Verify CNC/PLC diagnostic status.
- Check machine parameters and stored programs.
- Test manual and automatic operating modes.
- Perform a controlled production test.
❓ FAQ
Is 044340-2067 a Bosch CNC board?
Yes. It is identified in industrial spare-parts listings as a Bosch CNC/NC PLC-related circuit board.
What other numbers should be checked when purchasing this board?
The important identification markings include 044340-2067, 044339-301401, 048499-112401, and the associated Bosch number 1070048499-112.
Can this board replace every Bosch board with a similar appearance?
No. Similar Bosch boards may have different functions, revisions and interfaces. The complete part-number and hardware configuration should be matched.
Is it suitable for a machine retrofit?
It may be useful for legacy-machine repair or retrofit work, but compatibility should be verified against the complete CNC/PLC architecture before installation.
Should the original board be retained after replacement?
Yes. Keeping the original board is recommended because its markings, revision and connector configuration provide an important reference for future maintenance.

📦 Spare-Parts & Lifecycle Planning
For legacy Bosch CNC equipment, maintaining a small quantity of critical controller boards can significantly reduce unplanned downtime.
A practical spare-parts strategy includes:
- ABC classification: identify CNC CPU, PLC and control boards as high-priority components when their failure can stop production.
- Buffer stock: maintain at least one verified spare for critical machines where replacement lead time is uncertain.
- Incoming inspection: verify part number, PCB revision, connectors and physical condition before putting the spare into inventory.
- Functional testing: test replacement boards in a controlled environment whenever possible.
- Lifecycle planning: document installed board revisions and keep a cross-reference of alternative identification numbers.
- Last-time-buy planning: for discontinued CNC systems, consider purchasing additional tested spare boards before the remaining market supply becomes limited.
