Technical Specifications

Solving the Discontinued Hardware Crisis

The HE670 series occupied a defined role in Horner's legacy control lineup: compact, relay-based I/O integrated directly into operator control stations deployed across light manufacturing, water treatment, building automation, and material handling. When Horner discontinued this series, facilities running these controllers were left with a binary choice — source remaining inventory from the secondary market, or fund a full controls upgrade.

Condition & Reliability Assurance

Obsolete boards sourced from the secondary market carry real risk when not properly evaluated before installation. DriveKNMS applies a structured 5-step inspection protocol before any HE670RLY168C is released for shipment:

• Electrolytic Capacitor Assessment: Aging electrolytic capacitors are the primary failure mode in boards of this production era. Each unit is inspected for bulging, electrolyte leakage, and ESR deviation. Boards with degraded capacitors are either reconditioned or rejected from inventory.
• Firmware Version Verification: Where applicable, firmware or EPROM versions are confirmed against known-compatible revisions for the target Horner OCS platform to prevent version mismatch failures after installation.
• Pin and Connector Inspection: All edge connectors and relay socket pins are examined under magnification for oxidation, corrosion, and mechanical deformation. Affected contacts are cleaned or the board is rejected.
• Relay Contact Integrity Test: Relay coils and output contacts are actuated and tested for proper switching behavior and contact resistance within acceptable limits.
• Functional Burn-In: Boards are powered and cycled under controlled conditions prior to packaging to confirm stable operation before dispatch review.

Key Features for System Maintenance

• Drop-in replacement: The HE670RLY168C installs directly into the existing Horner OCS chassis without mechanical modification or field wiring changes.
• No reprogramming required: The host controller requires no logic changes. The replacement board assumes the same I/O map as the original — commissioning time is measured in minutes.
• No engineering rework: Field wiring connects to the same terminal positions. SCADA connections, HMI configurations, and field device wiring remain untouched.
• Avoids system-wide upgrade costs: Replacing this board preserves the entire existing control architecture and defers a six-figure capital project.
• Long-term asset protection: A verified spare in storage is the lowest-cost insurance available for a facility dependent on Horner OCS-based control. Secondary market availability for discontinued parts decreases over time — procurement now, at known cost, eliminates emergency sourcing risk.

How do I know the board is genuine and not a counterfeit or misrepresented unit?
All HE670RLY168C units in our inventory are sourced through verified industrial channels. Physical markings, board revision codes, and component layouts are cross-referenced against known-authentic references. Units that fail this verification are not offered for sale.

Should I purchase more than one unit?
For any facility operating more than one Horner OCS unit dependent on this board, holding at least one spare per critical control node is standard maintenance practice. This part is no longer manufactured. Secondary market availability will only decrease over time. Procurement at current pricing eliminates the risk of emergency sourcing at premium cost — or no availability at all.
