Solving the Discontinued Hardware Crisis

The Allen-Bradley 1336 PLUS and 1336 IMPACT drive families were workhorses of industrial automation through the 1990s and 2000s. Thousands of units remain in active service across water treatment facilities, paper mills, mining operations, and discrete manufacturing lines worldwide. The logic interface board is the communication and control backbone of these drives—it manages the interface between the drive's control circuitry and external command signals. Without a functioning 1336-L6/B, the drive cannot receive speed references, respond to start/stop commands, or communicate with the host PLC or DCS.

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

How to Extend Automation Asset Life by 5–10 Years Through Strategic Spare Parts Management

For plant managers and reliability engineers operating legacy Rockwell Automation infrastructure, the following framework has been applied successfully across multiple industrial sectors to defer costly system replacements while maintaining production reliability:

Condition & Reliability Assurance

DriveKNMS applies a 5-step quality assurance process to all obsolete boards before dispatch review. This process is designed specifically for the failure modes common to PCB assemblies that have been in storage or field service for extended periods.

Key Features for System Maintenance

• Drop-in replacement: The 1336-L6/B installs directly into the existing drive chassis using the original mounting points and connectors. No mechanical modification is required.
• No reprogramming required: Drive parameters stored in the drive's memory are not affected by a logic board replacement. The drive returns to its previous operating configuration without parameter re-entry, provided the drive's parameter memory is intact.
• No engineering redesign: Unlike a drive replacement or retrofit, a board-level repair does not require changes to the control panel wiring, PLC program, or process interlocks. Commissioning time is measured in hours, not days.
• Preserves existing safety certifications: Facilities operating under process safety management (PSM) or functional safety frameworks benefit from maintaining the original drive hardware, which avoids triggering re-validation requirements that a new drive installation would impose.

Q: Can you support multi-unit or repeat RFQ requests?
A: Yes. Send the model list, target quantity and destination so DRIVEKNMS can review sourcing options and quote the requirement as a project RFQ.

Can this board be used in both 1336 PLUS and 1336 IMPACT drives?
The 1336-L6/B is associated with the 1336 PLUS family. Compatibility with specific 1336 IMPACT configurations should be verified against the drive's catalog number and firmware revision before installation. Contact DriveKNMS for application-specific guidance.
