Allen-Bradley 1336-L5E – Digital Input Option Board | 1336 PLUS AC Drive Platform
Engineering Background
The Allen-Bradley 1336 PLUS series represents Rockwell Automation’s proven architecture for industrial AC variable-frequency drives deployed across discrete manufacturing, process control, and material handling applications. The 1336-L5E Digital Input Option Board extends the native I/O capability of the 1336 PLUS drive, enabling engineers to interface additional discrete control signals—such as preset speed selections, external fault inputs, and run/stop permissives—directly into the drive’s control logic without external relay panels or PLC I/O expansion modules.
Product Positioning
Designed for procurement engineers and maintenance teams managing legacy 1336 PLUS installations, the 1336-L5E (catalog numbers 42336-172-53 and 42336-173-53) is the OEM-specified option board for expanding digital input capacity. Sourced through verified industrial channels and inspected prior to shipment, this board is stocked at Konmask.com to support both planned upgrades and emergency replacement scenarios.

Proven Application Environments
- Conveyor & Material Handling: Multi-speed preset selection via digital inputs eliminates external speed-reference potentiometers and simplifies PLC ladder logic.
- Pump & Fan Control: External interlock and permissive signals (e.g., flow switch, pressure switch) wired directly to the option board for integrated drive-level fault management.
- Packaging Machinery: Synchronised start/stop and jog commands from machine safety relays routed through the 1336-L5E for deterministic response.
- HVAC & Building Automation: BAS digital outputs mapped to drive speed presets without additional I/O hardware.
- Legacy System Maintenance: Direct OEM-equivalent replacement for installed 1336 PLUS fleets, preserving existing wiring and parameter configurations.
Engineering Advantages
- Expanded I/O without external hardware: Adds discrete input channels directly on the drive, reducing panel footprint and wiring complexity.
- OEM-specified design: Fully compatible with 1336 PLUS firmware and parameter structure—no custom programming required.
- Plug-in installation: Seats into the drive’s internal option slot; no drive disassembly or firmware modification needed.
- Deterministic signal processing: Inputs are scanned synchronously with the drive’s control loop for reliable, low-latency response.
- Backward compatibility: Supports both 1336 PLUS and 1336 PLUS II platforms, protecting investment across drive generations.
System Architecture & Signal Flow
The 1336-L5E installs into the designated option board slot on the 1336 PLUS control board. Field wiring connects to the option board’s terminal strip, where each digital input channel is optically isolated from the drive’s internal logic. Input signals (typically 24 VDC sourced from a PLC output card or hardwired control circuit) are decoded by the option board’s onboard logic and passed to the drive’s parameter table via the internal backplane bus. The drive firmware maps these inputs to programmable functions—including multi-step speed references (Parameters 101–108), external fault (Parameter 111), and run/direction commands—without requiring any changes to the main control board wiring.
Signal flow summary: Field device → Terminal strip (1336-L5E) → Optical isolation → Backplane bus → Drive parameter mapping → Drive output control.
Sourcing & Quality Verification
- Traceability: Each unit is sourced from authorised distributors, OEM surplus channels, or verified industrial resellers with documented chain of custody.
- Incoming inspection: Visual inspection for physical damage, component integrity, and correct catalog number labelling prior to listing.
- Functional testing: Refurbished units undergo bench-level power-on and I/O verification against OEM specifications before shipment.
- Anti-counterfeit measures: Label authenticity, PCB markings, and component date codes are cross-checked against known-good reference units.
- Packaging: ESD-safe anti-static bag, foam-padded carton, and moisture-barrier seal for international shipment.

Technical FAQ
Q: Is the 1336-L5E compatible with the 1336 PLUS II drive?
A: Yes. The 1336-L5E is compatible with both the original 1336 PLUS and the 1336 PLUS II platforms. Confirm your drive’s option slot configuration before installation.
Q: Can I install multiple option boards simultaneously?
A: The 1336 PLUS supports up to two option boards depending on the drive frame size and existing option slot occupancy. Consult the 1336 PLUS User Manual (Publication 1336 PLUS-5.0) for slot assignment rules.
Q: What is the input voltage range for the digital inputs?
A: The 1336-L5E digital inputs are rated for 24 VDC nominal. Consult the option board installation sheet for exact voltage thresholds and current sink/source requirements.
Q: Do you provide installation documentation?
A: Yes. The Allen-Bradley installation sheet and relevant sections of the 1336 PLUS User Manual are available upon request. Contact our technical team at support@konmask.com.
Q: What warranty is provided?
A: All units carry a 12-month warranty from the shipment date covering manufacturing defects and functional failure under normal operating conditions.
