Solving the Discontinued Hardware Crisis

The INTERBUS protocol, while no longer in active development, remains embedded in thousands of production facilities worldwide — automotive body shops, food processing lines, pharmaceutical packaging systems, and water treatment plants among them. The IBS RT 24DI /16-T serves as a remote bus terminal collecting 16 digital input signals and transmitting them upstream through the INTERBUS ring topology. There is no generic substitute. The INTERBUS ring architecture requires protocol-native modules; inserting a non-compatible device breaks the ring and halts the entire network segment.

Extending the operational life of an INTERBUS-based system by 5 to 10 years through targeted spare parts procurement is not a workaround — it is a documented asset protection strategy. The capital expenditure deferred, combined with the time gained to plan a controlled migration on your own schedule, represents measurable financial value. The alternative — an unplanned failure with no spare available — forces emergency decisions under the worst possible conditions.

Condition & Reliability Assurance

Discontinued modules sourced from the secondary market carry inherent risk. DriveKNMS applies a structured 5-step inspection protocol before any unit is offered for sale:

• Step 1 – Visual and Mechanical Inspection: Housing integrity, connector pin condition, and label verification against the original part number.
• Step 2 – Electrolytic Capacitor Assessment: Aging electrolytic capacitors are a primary failure mode in modules of this generation. Each unit is inspected for capacitor bulging, leakage, and ESR deviation.
• Step 3 – Firmware Version Verification: Where accessible, firmware revision is confirmed to ensure compatibility with the target INTERBUS controller generation.
• Step 4 – Pin and Terminal Corrosion Check: All COMBICON terminals and bus connectors are inspected under magnification for oxidation, corrosion, and mechanical deformation.
• Step 5 – Functional Power-On Test: Units are powered and checked for correct initialization behavior prior to packaging.

Key Features for System Maintenance

How do I know the unit is genuine and not counterfeit?
All units are sourced through traceable industrial surplus channels. Physical markings, housing construction, and PCB characteristics are verified against known-good reference units. We do not source from unverified consumer marketplaces.
