PROFIBUS Communication and Industrial Control Integration

The DSQC 667 provides physical hardware for PROFIBUS network communication within compatible ABB automation equipment. Therefore, the host controller and installed firmware must support the specific board configuration.

The supplied documentation identifies the unit as a PROFIBUS Board but does not specify the PROFIBUS baud rate, connector pinout, electrical isolation characteristics, or supported firmware revisions. These parameters should be verified against the applicable ABB controller documentation before commissioning.

The board measures only 22.3 mm x 50.5 mm x 56.5 mm and has a net weight of 0.028 kg. Its compact dimensions support integration into controller assemblies where board-level installation space is limited.

Frequently Asked Questions (FAQ)

Q: What network protocol does the ABB 3HAC026840-001 support?

Q: What are the physical dimensions of the DSQC 667 board?
A: The listed product dimensions are 22.3 mm x 50.5 mm x 56.5 mm, with a product net weight of 0.028 kg.

Q: Is the operating temperature and power consumption specified?
A: No. The supplied product data does not state operating temperature limits or power consumption. Use the applicable ABB technical documentation for these values.

Field Installation Guidelines

• Confirm the controller assembly and hardware configuration before installing the board.
• Isolate controller power before performing physical board installation or removal.
• Install the board according to the mechanical orientation and retention method specified by the compatible ABB controller.
• Inspect the PROFIBUS connector and mating interface for contamination, mechanical damage, or loose contacts.
• Route PROFIBUS cabling separately from high-current motor, contactor, and switching-power wiring where practical.
• Maintain appropriate cable shielding and connect the shield according to the controller and PROFIBUS installation requirements.
• Avoid excessive cable bending or mechanical stress at the communication connector.
• Verify the PROFIBUS node configuration and controller firmware compatibility before commissioning.
• Do not apply operating power until the board is correctly seated and all required communication connections are secured.
