ABB DSTK153 26390603-G Industrial Ribbon Cable

Product Overview

The DSTK153 (26390603-G) is a factory-assembled ribbon signal cable engineered by ABB for internal signal interconnection within distributed control systems. It is primarily deployed in S800 I/O and AC 800M architectures, where stable analog signal transfer and mechanical reliability are essential. The cable is supplied by ABB as a dedicated accessory for multiple analog input and output kits, ensuring full electrical and mechanical compatibility with original system components.

This cable is not a generic field cable but an internal system interconnect designed to maintain signal integrity between I/O modules, terminal units, and interface boards inside control cabinets.

Design Characteristics and Function

The DSTK153 (26390603-G) is manufactured as a flat ribbon assembly with precisely matched conductors and factory-terminated connectors. Its geometry minimizes crosstalk between channels and supports low-level analog signal transmission in electrically noisy industrial cabinets. The cable length is optimized for standard ABB cabinet layouts, eliminating the need for on-site modification.

While some third-party distributors describe enhanced or modified versions, ABB’s official definition positions DSTK153 strictly as an internal system cable rather than a field-rated or IP-classified product.

Environmental sealing ratings such as IP67 and high-frequency impedance values are not defined in ABB’s official documentation and typically apply only to supplier-modified or application-specific variants.

System Compatibility

The DSTK153 (26390603-G) is supplied as part of, or fully compatible with, several ABB analog I/O kits, including:

• DSAX110 series analog input assemblies

• DSAO110 series analog output assemblies

• DSAO120 series analog output assemblies

It integrates seamlessly with ABB S800 I/O modules and AC 800M controllers without requiring configuration changes or adapter hardware.

Typical Applications

This ribbon cable is commonly used for:

• Internal wiring of ABB S800 I/O racks

• Analog signal routing within AC 800M control cabinets

• Interconnection between I/O modules and interface units

• Low-level voltage, current, and temperature signal paths

• Installations with elevated electromagnetic interference inside cabinets

FAQ

Is DSTK153 suitable for direct field wiring?
No. DSTK153 (26390603-G) is designed exclusively for internal system connections inside control cabinets. Field wiring requires separately rated and certified cables.

Can this cable be replaced with a generic ribbon cable?
Replacement with non-ABB cables is not recommended. Connector pinout, conductor spacing, and EMC behavior are specific to ABB I/O systems.

Why do some suppliers list different lengths or electrical values?
Those descriptions usually refer to third-party adaptations or customized assemblies. ABB’s standard DSTK153 is supplied as a fixed 3-meter internal cable.
