Technical Specifications

Solving the Discontinued Hardware Crisis

The Honeywell TDC 3000 platform was the backbone of process automation across petrochemical, refining, pulp and paper, and power generation industries from the 1980s through the 2000s. Tens of thousands of installations worldwide remain operational today — not because operators are unaware of newer alternatives, but because the cost and operational risk of full DCS migration is prohibitive for facilities running continuous or semi-continuous processes.

The DC-TEIM01 is the IOTA (I/O Termination Assembly) carrier for the Low Level Mux subsystem. It provides the physical termination point for thermocouple wiring and routes those signals into the LLMux scanning chain. Without a functional DC-TEIM01, the associated measurement points go dark. In a fired heater or distillation column application, losing temperature measurement is not a maintenance inconvenience — it is a process safety event.

How to extend your TDC 3000 asset life by 5 to 10 years — a practical framework for plant management:

This approach has allowed facilities across Southeast Asia, the Middle East, and Latin America to sustain TDC 3000 operations well beyond the platform's nominal end-of-life — deferring capital expenditure on DCS migration until it is strategically advantageous, not operationally forced.

Condition & Reliability Assurance

Every DC-TEIM01 unit shipped by DriveKNMS passes a structured 5-step quality verification process before dispatch. This protocol was developed specifically for legacy I/O hardware where manufacturer support is no longer available.

1. Visual and mechanical inspection. Full examination of the IOTA board, connector pins, and backplane interface for physical damage, corrosion, and mechanical deformation. Units with pin oxidation are rejected or remediated before proceeding.
2. Electrolytic capacitor assessment. Capacitor aging is the primary failure mode in hardware of this vintage. Each unit is inspected for capacitor bulging, leakage, and ESR degradation. Units with suspect capacitors are either recapped with equivalent-spec components or quarantined.
3. Firmware and label verification. Hardware revision markings and any embedded firmware identifiers are documented and cross-referenced against known-compatible TDC 3000 system revisions.
4. Connector and termination integrity check. All field wiring termination points are inspected for corrosion, loose hardware, and contact integrity. Connector blocks are cleaned and verified.
5. Functional bench test. Where test equipment permits, units are powered and signal continuity is verified across the multiplexer chain. Test results are logged and accompany the shipment.

Units that do not pass all five stages are not offered for sale. Condition is disclosed accurately — new surplus units are identified as such; refurbished units are documented with the work performed.

Key Features for System Maintenance

Q: How are RFQ terms confirmed?
A: Quantity, required condition, documentation needs, destination and sourcing route are confirmed during RFQ review before quotation.
