Technical Specifications

Note: Electrical parameters such as input range, channel count, and bus interface specifications are confirmed against physical unit markings and original Siemens documentation prior to shipment. No parameters are published here that have not been independently verified.

Solving the Discontinued Hardware Crisis

The Siemens TELEPERM M platform reached end-of-life status decades ago, yet thousands of units remain in active service across refineries, chemical plants, and power stations worldwide. The architecture of TELEPERM M — with its proprietary SINEC bus structure and module-specific firmware — means that individual I/O cards such as the 6DS1723-8BB cannot be substituted with generic modern hardware without a full system migration.

Plant managers operating TELEPERM M installations face a structural dilemma: the cost of a full DCS migration is prohibitive, yet the supply of original spare modules shrinks every year as other facilities decommission their systems. Each unit that leaves the secondary market permanently reduces the global pool of available spares.

DriveKNMS sources TELEPERM M modules through controlled decommissioning projects and verified industrial surplus channels. Each unit undergoes condition assessment before it enters our inventory. We do not list modules we cannot physically inspect.

Condition & Reliability Assurance

Obsolete modules sourced from the secondary market carry inherent risks that differ from new production components. Our 5-step QA process addresses the failure modes specific to aged industrial electronics:

• Step 1 – Visual and Mechanical Inspection: Board-level examination for physical damage, corrosion on edge connectors and pin contacts, and evidence of prior field repairs or unauthorized modifications.
• Step 2 – Electrolytic Capacitor Assessment: Electrolytic capacitors are the primary age-related failure point in modules of this era. Each board is assessed for capacitor bulging, leakage residue, and ESR deviation. Units with compromised capacitors are either recapped by qualified technicians or removed from saleable inventory.
• Step 3 – Firmware and Label Verification: The firmware version and hardware revision markings are cross-referenced against Siemens documentation to confirm compatibility with the target system configuration. Mismatched firmware revisions are a known source of intermittent faults in TELEPERM M installations.
• Step 4 – Pin and Connector Integrity: All backplane connector pins are inspected under magnification for oxidation, mechanical deformation, and solder joint integrity. Contact surfaces are cleaned where required.
• Step 5 – Functional Verification: Where test equipment permits, modules are powered and basic functional checks are performed. Test results are documented and available to the buyer on request.

Key Features for System Maintenance

Q: How do I confirm the unit is genuine Siemens and not a counterfeit?
A: All units are sourced from traceable industrial decommissioning projects or verified surplus dealers. Siemens part markings, board silk-screen references, and hardware revision labels are inspected and photographed. Documentation is provided with each shipment on request.

Q: Can you source other TELEPERM M modules?
A: Yes. DriveKNMS maintains an active sourcing network for the full TELEPERM M range. Contact us with your complete bill of materials and we will advise on availability.
