Allen-Bradley 74101-954-53 (1336T-GT3EN) – Control Board Drive | 1336 PLUS Series
Engineering Background
The Allen-Bradley 1336 PLUS series represents Rockwell Automation’s proven generation of AC variable-frequency drives, widely deployed across discrete manufacturing, process control, and material handling applications globally. The 74101-954-53 (1336T-GT3EN) is the dedicated control board assembly for this platform, serving as the central intelligence layer that governs PWM switching, speed regulation, fault diagnostics, and serial communications.
Product Positioning
This control board is the critical replacement component for 1336 PLUS drive systems experiencing control-layer failures — including communication faults, parameter loss, or gate-drive signal anomalies — without requiring full drive replacement. Procurement engineers sourcing this board can restore drive functionality at a fraction of the cost of a new drive unit.

- Proven Field Reliability — 1336 PLUS platform has 20+ years of documented industrial deployment across global facilities
System Architecture & Signal Flow
The 74101-954-53 control board interfaces with the 1336 PLUS drive chassis at the following signal boundaries:
- Gate Drive Interface — Generates PWM firing signals to the IGBT/transistor power module; signal integrity directly governs motor output waveform quality
- Analog I/O — Accepts speed reference (0–10 VDC / 4–20 mA) and outputs process feedback signals to supervisory control systems
- Digital I/O — Interfaces with run/stop, fault reset, and multi-speed preset inputs from PLC or operator station
- Serial Communications Port — DH-485 or RIO network connection for parameter read/write and drive status monitoring from RSLogix/RSNetWorx
- Feedback Interface — Encoder or tachometer input for closed-loop speed/torque regulation (drive-configuration dependent)
Sourcing & Quality Verification
- Authenticity — All boards sourced from authorized dismantlers, OEM overstock, or certified repair facilities; counterfeit screening performed on every unit
- Functional Testing — Boards undergo power-on verification and communication port integrity checks prior to shipment

Technical FAQ
Q: Is the 74101-954-53 compatible with all 1336 PLUS drive ratings?
A: The 1336T-GT3EN control board is designed for the 1336 PLUS (1336T) platform. Compatibility across specific horsepower ratings and firmware revisions should be confirmed against the drive’s existing board revision. Contact our technical team for cross-reference support.
Q: Will I need to re-enter drive parameters after replacing the control board?
A: Yes. While the EEPROM retains parameters through power cycles, a board swap requires re-commissioning. We recommend backing up parameters via DriveExplorer or RSLogix 5000 before removal.
Q: Can this board be repaired rather than replaced?
A: Board-level repair is possible for certain failure modes (capacitor replacement, trace repair). Konmask can advise on repair vs. replace economics based on your failure description.
Q: What is the typical lead time?
A: In-stock units ship within 1–2 business days. Out-of-stock units typically have a 2–4 week sourcing lead time. Contact us for real-time availability.
Q: Do you provide a certificate of conformance?
A: Yes. A certificate of conformance and test report are available upon request for quality-system compliance.
