Allen-Bradley 1336T-GT1-SP34B — Control Board Drive | 1336 PLUS Series
工程背景 / Engineering Background
The Allen-Bradley 1336 PLUS series represents Rockwell Automation’s proven architecture for AC variable frequency drive (VFD) control in demanding industrial environments. The 1336T-GT1-SP34B control board serves as the central intelligence layer of the 1336T drive platform, coordinating gate trigger signals, feedback loops, and communication interfaces across the drive’s power stage. Companion boards 1336T-LM1EN, 74103-015-52A, and 74101-954-52C form an integrated control assembly commonly replaced as a matched set during drive refurbishment or fault recovery.
产品定位 / Product Positioning
Sourced for OEM-grade replacement and MRO (Maintenance, Repair & Operations) procurement, this control board assembly is suited for facilities maintaining legacy 1336T drive infrastructure where downtime cost exceeds new-drive capital expenditure. Konmask.com supplies verified, traceable units to B2B industrial buyers, system integrators, and OEM service teams globally.

- Reduced Downtime — ready-to-install units reduce MTTR (Mean Time to Repair) versus waiting for OEM lead times of 8–20 weeks
- Functional Test Protocol — each unit undergoes power-on verification and gate signal continuity check prior to dispatch
- Traceability — part markings, revision codes, and inspection records provided with shipment documentation
- Global Logistics — EXW Xiamen; DDP available to major industrial hubs; DHL / FedEx / freight forwarder compatible
System Architecture & Signal Flow
Within the 1336T drive platform, the GT1-SP34B board occupies the control tier, receiving speed reference and torque commands from the operator interface or network adapter (SCANport/DPI). It generates PWM gate trigger signals distributed to the IGBT/SCR power module via the gate driver board. The LM1EN board provides the logic-to-power interface and analog I/O conditioning. Boards 74103-015-52A and 74101-954-52C handle auxiliary feedback, fault detection, and protection relay outputs. Together, this four-board assembly constitutes the complete control intelligence of the 1336T drive frame.

Technical FAQ
Q: Can the 1336T-GT1-SP34B be used as a standalone replacement without the companion boards?
A: In some fault scenarios, only one board requires replacement. However, when the root cause is unclear or multiple fault codes are present, replacing the full matched set (GT1-SP34B + LM1EN + 74103-015-52A + 74101-954-52C) is the recommended engineering practice to eliminate inter-board fault propagation.
Q: Is firmware programming required after board replacement?
A: The 1336T control board stores drive parameters in non-volatile memory on the board itself. After replacement, parameters must be re-entered or restored from a previously saved parameter file using DriveExplorer or DriveExecutive software. Konmask can provide parameter backup templates for common 1336T configurations upon request.
Q: What is the typical lead time for this assembly?
A: In-stock units ship within 1–3 business days from Xiamen, China. If sourcing is required, lead time is 5–15 business days. Expedited sourcing available for critical downtime situations.
Q: Do you provide installation support?
A: Yes. Konmask’s technical team can provide installation guidance, wiring diagrams, and Rockwell Automation documentation references via email. On-site commissioning support can be arranged through our partner network for qualified projects.
Q: What certifications does this product carry?
A: The original Allen-Bradley 1336T platform carries UL, CE, and CSA certifications. Refurbished/surplus units retain original markings; Konmask provides CoC documentation. Buyers in regulated industries should verify certification status with their compliance team prior to installation.
