Allen-Bradley 1336-C003-EOD Replacement for 1336 PLUS Series

Product Overview

Allen-Bradley 1336-C003-EOD Replacement for 1336 PLUS Series: Smooth Transition & Legacy System Compatibility

The Allen-Bradley 1336-C003-EOD is a 0.37 kW (0.5 HP) AC variable frequency drive from the 1336 PLUS series, a platform that has reached end-of-life status across most Rockwell Automation distribution channels. For facilities still operating legacy motor control systems built around the 1336 PLUS family, sourcing a verified replacement unit is critical to maintaining production continuity without committing to a full drive system overhaul.

TOPNLMS supplies the 1336-C003-EOD as a tested, shelf-ready replacement module. Each unit is inspected prior to dispatch and ships with a 12-month warranty covering manufacturing defects and functional failure under normal operating conditions. Our inventory is sourced from authorized surplus channels and verified against original Rockwell Automation specifications, making this an ideal solution for maintenance engineers managing aging control infrastructure.

Seamless Upgrade Solutions

When migrating a legacy motor control system built around the 1336 PLUS platform, the 1336-C003-EOD rarely operates in isolation. In most panel configurations, this drive shares a control cabinet with a ControlLogix or SLC 500 controller backplane, and the upgrade process requires careful coordination across several interconnected components.

For facilities using a 1756-L61 or 1756-L71 ControlLogix processor as the supervisory controller, the SCANport interface on the 1336-C003-EOD can be bridged using a 1203-USB or 1203-GU6 SCANport-to-USB adapter, allowing parameter upload and comparison before the replacement unit is installed. This step is strongly recommended to preserve existing ramp times, current limits, and fault response configurations without manual re-entry.

In systems where the 1336 PLUS communicates over a DeviceNet network alongside other field devices — such as 1769-SDN scanner modules or 1747-SDN SLC DeviceNet scanners — the replacement drive should be configured with a matching node address and baud rate before commissioning. The 1336-D-N DeviceNet adapter, if already installed on the outgoing unit, can typically be transferred directly to the 1336-C003-EOD without modification.

Power distribution within the control cabinet often involves a 1606-XLP power supply or similar 24 VDC control power source feeding the drive’s logic board and I/O interface. Verifying that the existing power supply rail can support the replacement unit’s control power draw is a standard pre-installation check that prevents nuisance faults during initial startup.

For sites where the 1336 PLUS drives are mounted in a multi-drive enclosure alongside 1336 IMPACT or 1336 FORCE series units, the physical footprint of the 1336-C003-EOD is compatible with standard 1336-series mounting hardware. No enclosure modification is required for a like-for-like swap, which significantly reduces planned downtime during the replacement window.

If the broader migration roadmap includes transitioning from the 1336 PLUS platform to a PowerFlex 4M or PowerFlex 40 series drive, the 1336-C003-EOD serves as a reliable interim solution — maintaining production while the new drive program is developed, tested, and validated in a parallel environment. Terminal block wiring on the 1336-C003-EOD follows the standard 1336 PLUS layout, and most existing motor cable terminations can be reused without re-pulling wire.

Sites using a 1336-GM1 or 1336-GM2 operator interface panel will find that the replacement unit retains full HIM compatibility, allowing operators to continue using familiar parameter navigation without retraining. For remote monitoring applications, the 1336-C003-EOD supports connection to a 1336-L3 or 1336-L5 communication module for integration into existing DH+ or ControlNet architectures.

Retrofit Guidance FAQ

Q: Can I reuse existing motor wiring when replacing the 1336-C003-EOD?
A: Yes. The output terminal layout (T1/T2/T3) on the 1336-C003-EOD matches the standard 1336 PLUS wiring convention. Existing motor cables can be reconnected directly without modification, provided cable insulation ratings are within specification for the drive’s output switching frequency.

Q: Will my existing SCANport HIM work with the replacement unit?
A: Yes. The 1336-C003-EOD uses the standard SCANport interface. Any 1336-series HIM — including the 1336-MOD-D010 or 1336-MOD-D020 — will communicate with the replacement unit without firmware changes.

Q: How do I transfer parameters from the failed drive to the replacement?
A: Use DriveExplorer or DriveExecutive software via a 1203-USB adapter to upload parameters from the original unit if it is still partially functional. If the original unit is non-responsive, TOPNLMS can provide a baseline parameter file for the 1336-C003-EOD upon request.

Q: Is the 1336-C003-EOD compatible with DeviceNet networks?
A: The base unit uses SCANport. DeviceNet connectivity requires the 1336-D-N adapter module. If your existing installation already includes this adapter, it can be transferred to the replacement unit.

Q: What is the physical installation space requirement?
A: The 1336-C003-EOD uses the standard 1336 PLUS panel-mount footprint. No enclosure modification is required for a direct replacement. Verify minimum clearance distances (top, bottom, and sides) per the 1336 PLUS installation manual for adequate airflow.

Q: Can this unit be used as a direct replacement for 1336-B003 series drives?
A: The 1336-C003-EOD is functionally equivalent to earlier 1336-B003 variants at the same power rating. Wiring, mounting, and SCANport communication are compatible. Review firmware revision differences if your system uses advanced parameter features specific to the B-series.

Warranty Assurance

Every 1336-C003-EOD unit supplied by TOPNLMS is covered by a 12-month warranty from the date of shipment. Prior to dispatch, each unit undergoes a functional inspection including power-on verification, output phase check, and SCANport communication test. Units that do not pass inspection are not shipped.

In the event of a warranty claim, TOPNLMS provides a replacement unit or full refund depending on the nature of the fault and the customer’s preference. Warranty claims are processed within 3 business days of fault confirmation. Return shipping for defective units is covered by TOPNLMS for the first warranty claim per order.

For time-critical maintenance situations, TOPNLMS offers priority dispatch with same-day or next-business-day shipping from Xiamen for in-stock units. Customers requiring expedited handling should contact our sales team directly to confirm stock availability and shipping lead time before placing an order.

Bulk procurement customers — including MRO distributors, system integrators, and OEM panel builders — are eligible for volume pricing and extended payment terms. Contact our team to discuss project-specific requirements, including kitting, pre-configuration, and consolidated shipment options.
