Technical Specifications

Note: Specific electrical parameters (voltage ratings, I/O counts, communication protocols) vary by sub-assembly. Confirmed specifications are provided upon request with unit serial number verification. No parameters are published here without direct confirmation against physical units.

Solving the Discontinued Hardware Crisis

The PRESYS TH-220 platform was widely deployed across Latin American and Asian process industries through the 1990s and 2000s. Its modular architecture — with board-level components such as the C0525 and V70-P sub-assemblies — made it a reliable workhorse for temperature and process variable control in environments where stability mattered more than cutting-edge features.

When PRESYS discontinued the TH220 line, facilities running these controllers faced a hard choice: absorb the capital expenditure of a full DCS migration, or find a way to extend the operational life of existing assets. For most plant managers operating under tight maintenance budgets and multi-year capital approval cycles, migration is not a near-term option.

The practical path forward is component-level maintenance. Keeping a verified spare of the C0525 board assembly or the V70-P module on the shelf means that when a failure occurs — and in aging systems, failure is a matter of when, not if — the response is a swap, not a crisis. Production resumes in hours rather than weeks. The engineering team avoids an emergency procurement scramble. The capital budget remains intact for planned upgrades.

Facilities that have successfully extended PRESYS TH-220 system life by 5 to 10 years beyond OEM support end-of-life share a common approach: they treat critical spare parts as insurance assets, not consumables. A single spare module, properly stored, can prevent a production loss event that costs 50 to 100 times its purchase price. For plant managers facing board-level pressure to defer system replacement, this is the most defensible maintenance strategy available.

Condition & Reliability Assurance

Every PRESYS TH-220 series unit processed by DriveKNMS goes through a structured 5-step inspection protocol before it is offered for sale or shipment:

• Step 1 – Visual and Mechanical Inspection: Full board-level examination for physical damage, corrosion, pin deformation, and connector integrity. Units with compromised housings or oxidized contact surfaces are rejected at this stage.
• Step 2 – Electrolytic Capacitor Assessment: Aging electrolytic capacitors are the primary failure mode in legacy process control boards. Each capacitor is checked for bulging, leakage, and ESR deviation. Suspect capacitors are replaced with specification-matched components before the unit proceeds.
• Step 3 – Firmware and Configuration Verification: Where applicable, firmware version is confirmed and documented. Units are not shipped with unknown or corrupted firmware states.
• Step 4 – Pin and Connector Corrosion Remediation: All edge connectors and pin headers are cleaned and treated. Contact resistance is verified to be within acceptable limits for reliable signal integrity in the target application.
• Step 5 – Functional Verification: Units are powered and tested under controlled conditions. Only units that pass functional verification are classified as Ready-to-Ship.

Units that do not pass all five steps are either remediated to standard or removed from inventory. Condition grade is disclosed on the invoice.
