Allen-Bradley 1336-L5E Replacement for 1336 PLUS Drive

Product Overview

Allen-Bradley 1336-L5E Replacement for 1336 PLUS AC Drive: Seamless Transition & Compatible Upgrade

The Allen-Bradley 1336-L5E (also catalogued as 42336-172-53 and 42336-173-53) is a Digital Input Option Board designed for the Rockwell Automation 1336 PLUS series AC variable-frequency drive. As the 1336 PLUS platform approaches end-of-life and spare parts become increasingly scarce, plant engineers and maintenance teams across manufacturing, water treatment, HVAC, and process industries are actively seeking verified replacement and upgrade paths that minimize downtime, preserve existing wiring infrastructure, and protect capital investment in control-panel real estate.

TOPNLMS stocks the 1336-L5E and its functional equivalents, fully tested and ready to ship from Xiamen, China, with a 12-month warranty covering defects in materials and workmanship. Whether you are executing a like-for-like spare replacement or planning a phased migration to a current-generation drive platform, this page provides the technical guidance, compatibility data, and procurement assurance you need to move forward with confidence.

Seamless Upgrade Solutions

A successful 1336-L5E replacement or drive-platform migration rarely involves a single component. In practice, field engineers working on 1336 PLUS retrofit projects encounter a predictable set of associated components that must be sourced, tested, and staged alongside the digital input option board.

The 1336 PLUS drive itself — whether a 1336-B, 1336-S, or 1336-BRF frame variant — houses the option board in a dedicated internal slot. When the drive chassis is also being replaced, the 1336-L5E must be re-evaluated against the new host platform. For customers migrating to the 1336 PLUS II series, the 1336F-L5E is the direct functional successor and shares the same terminal layout, simplifying wiring re-use.

Communication architecture is a common migration concern. Many 1336 PLUS installations rely on a 1336-GM1 or 1336-GM6 communication module for DeviceNet or Remote I/O connectivity. When upgrading to PowerFlex 40 or PowerFlex 400 drives, the equivalent 22-COMM-D (DeviceNet) or 22-COMM-E (EtherNet/IP) adapter modules must be specified to maintain PLC network topology without reprogramming the upstream Allen-Bradley ControlLogix or SLC 500 controller.

On the power side, the 1321-3R line reactor and 1321-3RA EMC filter assemblies commonly installed upstream of 1336 PLUS drives are typically retained during a like-for-like board replacement, but must be re-rated if the drive frame size changes during a full platform upgrade. Similarly, the 1336-MOD-L2 brake resistor module and associated dynamic braking hardware should be inspected and re-verified for compatibility with any replacement drive.

For installations where the 1336 PLUS interfaces with a PanelView 550 or PanelView 600 HMI over DH-485 or Remote I/O, the communication path through the 1747-AIC link coupler or 1747-KE DH-485/RS-232 interface module must be preserved or re-routed during migration. TOPNLMS can supply these ancillary communication components as part of a consolidated migration kit, reducing lead time and simplifying incoming inspection.

Terminal block assemblies — particularly the 1492-CABLE series wiring systems and 1492-IFM interface modules — are frequently required when re-terminating field wiring after a drive or option board swap. Sourcing these alongside the 1336-L5E from a single supplier eliminates coordination delays and ensures all components arrive together for a scheduled maintenance window.

Retrofit Guidance FAQ

Q: Can I install the 1336-L5E without modifying existing field wiring?
A: Yes, in a like-for-like replacement scenario. The 1336-L5E uses a standard terminal block with 24 VDC discrete inputs. As long as the replacement board is the same catalog revision, field wiring can be transferred directly. Always verify terminal numbering against the original drive documentation before powering up.

Q: Do I need to re-program the 1336 PLUS drive after replacing the option board?
A: Typically no, if the replacement board is the same catalog number and firmware revision. The drive’s parameter set is stored in the main control board, not the option board. However, we recommend verifying all digital input parameter assignments (Parameters 161–166 in the 1336 PLUS firmware) after installation to confirm correct mapping.

Q: What communication protocols does the 1336-L5E support?
A: The 1336-L5E is a hardwired discrete digital input board and does not carry a fieldbus protocol. Network communication (DeviceNet, Remote I/O, DH+) is handled by a separate communication option board installed in a different slot of the 1336 PLUS chassis. The two boards operate independently.

Q: Will the 1336-L5E fit in all 1336 PLUS frame sizes?
A: The 1336-L5E is compatible with all standard 1336 PLUS frame sizes (A through F) that include an option board slot. Verify your drive’s option board slot availability in the 1336 PLUS User Manual (Publication 1336 PLUS-5.0) before ordering.

Q: What if my 1336 PLUS drive is beyond repair and I need to migrate to a current-generation platform?
A: TOPNLMS recommends evaluating the PowerFlex 40 or PowerFlex 400 as migration targets. Both platforms offer equivalent digital I/O expansion capability, modern EtherNet/IP connectivity, and are supported under Rockwell Automation’s current TechConnect program. Contact our technical team at [email protected] for a migration BOM and compatibility assessment.

Q: How do I verify the physical installation space in my control panel?
A: The 1336-L5E occupies the option board slot inside the 1336 PLUS drive enclosure — it does not require additional panel space. The drive’s external dimensions remain unchanged. If you are replacing the entire drive, consult the dimensional drawings for the target platform to confirm panel cutout and DIN rail compatibility.

Warranty Assurance

Every 1336-L5E unit shipped by TOPNLMS is covered by a 12-Month Warranty from the date of delivery. Our pre-shipment inspection process includes functional verification of all discrete input channels, visual inspection for component damage, and confirmation of catalog number and revision markings against the order specification.

In the event of a warranty claim, TOPNLMS provides a replacement unit or full refund at our discretion, with return shipping coordinated by our after-sales team. Typical warranty response time is 1–3 business days from claim submission. We maintain buffer stock of high-demand 1336 PLUS option boards specifically to support rapid warranty replacements without extended lead times.

For procurement teams requiring documentation, we can provide a Certificate of Conformance, packing list, and commercial invoice with each shipment. Export from Xiamen, China is handled via DHL, FedEx, or UPS Express, with typical transit times of 3–7 business days to most destinations worldwide. Customs documentation is prepared in compliance with HS Code 8537.10 for programmable controllers and associated option modules.
