ABB DSTK150 26390603-A Flat Cable Assembly

Overview

The DSTK150 (26390603-A) is an ABB-supplied prefabricated flat-cable assembly engineered for internal signal interconnection in Advant and AC 800M control platforms. It is designed to link system modules through standardized EUROCONC96 interfaces, ensuring consistent electrical performance and mechanical reliability within control cabinets.

While some third-party catalogs describe this part number as a Profibus-DP interface, ABB’s original documentation and customs classification clearly identify DSTK150 (26390603-A) as a cable assembly, not an active communication module. Any association with Profibus networks typically arises from system integration contexts rather than from the cable itself containing protocol electronics.

Functional Role in Control Systems

The DSTK150 (26390603-A) functions as a passive interconnection component. It carries digital and control signals between compatible ABB modules mounted in racks or cabinets. Its flat-cable design minimizes space usage and simplifies routing while maintaining signal integrity in electrically noisy industrial environments.

This cable is commonly installed inside automation enclosures where stable, vibration-resistant connections are required for long-term operation.

Clarification on Profibus-DP References

The DSTK150 (26390603-A) does not contain RS-485 transceivers, isolation circuitry, LEDs, firmware, or power electronics. Specifications such as baud rate, node count, isolation voltage, or IP protection belong to active Profibus-DP interface modules, not to this cable assembly.

In practice, some distributors list this part alongside Profibus communication hardware because it is often supplied or installed in systems that include Profibus-DP modules. This contextual association should not be interpreted as a functional equivalence.

Typical Applications

• Internal rack-to-rack or module-to-module wiring

• Signal routing within AC 800M and Advant control systems

• Cabinet-level interconnection in process automation installations

• Long-term fixed installations requiring stable mechanical retention

Industries commonly using this cable include power generation, chemical processing, water treatment facilities, and continuous-process manufacturing plants.

FAQ

Is DSTK150 (26390603-A) a Profibus-DP communication module?
No. It is a passive flat-cable assembly. Any Profibus functionality is provided by separate interface modules.

Can this cable be replaced with a standard ribbon cable?
Direct substitution is not recommended. The EUROCONC96 connector quality, pin alignment, and insulation characteristics are designed to meet ABB system requirements.

Is the cable suitable for field installation?
No. It is intended for internal cabinet or rack installation in controlled industrial environments.
