🏭 Hydraulic Control System Integration
The VT-SWKD family is associated with digital command-value and control electronics used in Rexroth hydraulic systems. Rexroth documentation lists VT-SWKD-1 as a digital command-value card family, while related VT-SWKD variants are used within dedicated hydraulic control architectures.
When installed as part of a complete control assembly, the base board provides the electrical and mechanical platform for the associated electronic circuitry. The daughter board configuration is particularly important because the complete assembly may depend on the specific revision and connected control modules.
For replacement work, technicians should compare:
- Complete ordering code
- Board revision and identification labels
- Daughter-board part number
- Connector arrangement
- Backplane or rack interface
- Associated Rexroth controller/card holder
- Existing machine wiring
- Hydraulic valve and feedback configuration
A visually similar VT-SWKD board should not automatically be treated as interchangeable.
🔌 Control & Interface Considerations
The VT-SWKD-1-13/V0/0 should be considered a system-level replacement component, rather than a generic standalone PLC board.
Before commissioning, verify the complete signal path between the control board and the machine:
Controller → VT-SWKD electronics → hydraulic control stage → valve/actuator → machine feedback
Particular attention should be given to:
- Command-value signals
- Feedback signals
- Supply and reference voltages
- Board-to-board connections
- Rack/backplane connections
- Connector pin assignments
- Shielding and grounding
- Existing controller configuration
Incorrect wiring or installation of a board with a different revision can result in incorrect hydraulic commands or failure of the control loop.
🧩 Base Board & Daughter Board Function
The base-board/daughter-board construction allows the control electronics to be organized into a compact modular assembly.
The base board generally provides the primary electrical and mechanical platform, while the associated daughter board can carry additional circuitry required by the particular controller configuration.
For maintenance purposes, the complete assembly should therefore be treated as a matched configuration. Do not separate or replace the daughter board without checking the original assembly identification.
This is especially important when servicing older Rexroth equipment where multiple VT-SWKD variants have similar physical appearances but different suffixes.
🏗️ Typical Applications
The VT-SWKD-1-13/V0/0 may be encountered in legacy Rexroth hydraulic control installations such as:
- Industrial hydraulic presses
- Machine tools
- Hydraulic positioning systems
- Servo-hydraulic machinery
- Closed-loop hydraulic control equipment
- Industrial forming machinery
- Specialized NC hydraulic systems
- Legacy Rexroth control cabinets
The exact application depends on the complete machine configuration and associated Rexroth electronics.
🛠️ Installation & Maintenance
Before replacing the board:
- Shut down the machine using the approved machine procedure.
- Isolate incoming electrical power.
- Confirm that stored electrical energy has been discharged.
- Document connector positions and cable routing.
- Record the original board and daughter-board markings.
- Compare the replacement part number and revision.
- Inspect connectors for oxidation, bent contacts, or contamination.
- Check the PCB for cracked components or mechanical damage.
- Install the board without forcing connectors or mounting hardware.
- Recheck all connections before energizing the system.
After installation, verify controller status and machine behavior before returning the hydraulic system to automatic operation.
🔍 Troubleshooting
Board is not recognized
Check the board identification, daughter-board connection, rack position, connector seating, and associated control electronics.
Hydraulic output is incorrect
Verify command-value wiring, signal polarity, reference voltage, controller configuration, and the compatibility of the installed board revision.
Intermittent operation
Inspect connectors, PCB contacts, backplane connections, grounding, and possible contamination or vibration-related mechanical issues.
Replacement board does not operate
Do not assume that a board with a similar VT-SWKD designation is interchangeable. Compare the complete ordering code, suffix, revision, daughter-board configuration, and associated controller.
Machine remains in fault condition
Check the complete control chain rather than replacing the board repeatedly. The fault may originate from the power supply, feedback device, valve electronics, wiring, or another controller module.
🔐 Replacement Compatibility
Compatibility should be confirmed using the complete part number VT-SWKD-1-13/V0/0 and the actual board configuration.
Related variants such as VT-SWKD-1-13A/V0/0, VT-SWKD-1-13B/V0/0, and other VT-SWKD assemblies should not be assumed to be direct substitutes. Available listings show that these variants can be associated with different controller-card or base-board configurations.
For a reliable replacement, match the original assembly by:
- Full model number
- Revision
- Daughter-board marking
- Connector arrangement
- Controller/card-holder type
- Machine application
❓ FAQ
Q1: What is the VT-SWKD-1-13/V0/0?
It is a Bosch Rexroth control board associated with the VT-SWKD family of digital hydraulic control electronics.

📌 Spare-Part Recommendation
For legacy Rexroth hydraulic equipment, keeping a correctly matched VT-SWKD control assembly in spare inventory can reduce downtime when a board-level failure occurs.
For critical machines, record the complete board identification and daughter-board configuration as part of the equipment spare-parts database. When purchasing a replacement, compare the physical board, connectors, revision, and associated controller rather than relying only on a similar-looking product photograph.
The BOSCH REXROTH VT-SWKD-1-13/V0/0 is best treated as a configuration-specific industrial control spare, making exact part-number verification essential before installation.
