More Information

Overview Manuals Input Logic Wiring Compatibility Application
  • Reported /B variant of the verified 1336-L6 115 V AC interface board
  • Nine programmable control inputs on the L-option interface
  • L6 function excludes the encoder terminals provided by L6E variants

1336-L6/B is reported as a Series B or /B version of the 1336-L6 115 V AC control-interface board.

Official documents verify the base 1336-L6 function, nine programmable inputs, electrical thresholds, and compatible PLC output examples, but not the exact /B suffix.

Publication should wait for a readable product label or official order record confirming the complete suffix and the board's host-drive compatibility.

Availability, condition, price, and shipping time for 1336-L6/B are confirmed during quotation.

  • Confirm every assigned input function in the drive parameters
  • Identify the external control supply and all return conductors
  • Check PLC-output leakage, commons, isolation, and protective devices
  • Follow stored-energy and lockout procedures before wiring changes
  • Verify the complete host-drive catalog number and series
  • Do not substitute L6E when encoder terminals are required or absent
  • Confirm the reported /B suffix from a readable label or official record
  • 115 V AC discrete command interfacing for a compatible Bulletin 1336 drive
  • PLC relay or AC output connection to programmable 1336 control inputs
  • 120 V AC enable and interlock signaling in verified 1336 drive or regeneration systems
Description
Allen-Bradley 1336-L6/B is a 115 V AC high-true logic control interface board for compatible Bulletin 1336 PLUS, PLUS II, FORCE, and IMPACT drive systems.

The board provides nine programmable discrete inputs connected through terminal block TB3. Its input circuits are optically isolated from the drive logic and can be assigned functions such as start, stop, reverse, jog, reset, enable, preset speed selection, alternate acceleration and deceleration, or local control selection. The L6 configuration does not provide encoder-feedback terminals.

Before installing or replacing 1336-L6/B, confirm the complete catalog number, compatible 1336 drive family, drive hardware and firmware, 115 V AC control supply, TB3 terminal assignments, external field wiring, programmed input functions, and required machine-safe response. Do not interpret the /B suffix as a confirmed hardware Series unless it is supported by the product label or model-specific manufacturer documentation.

Technical notes
Allen-Bradley 1336-L6/B remains pending until /B is verified; base 1336-L6 uses nine 115 V AC inputs without encoder terminals.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
What must be matched before ordering Allen-Bradley 1336-L6/B?
Provide the complete drive catalog number, drive family, frame, installed interface-board label, terminal photographs, existing option boards, control-voltage source, and machine wiring diagram before confirming compatibility.
How does Allen-Bradley 1336-L6/B differ from an L6E board?
The verified L6 specification provides 115 V AC control inputs without encoder terminals. L6E adds encoder-related terminals; confirm the host drive and required feedback architecture.
Will replacing Allen-Bradley 1336-L6/B preserve the existing drive setup?
Do not rely on the board change alone to preserve operation. Record drive parameters, input assignments, jumpers, terminal wiring, interlocks, option hardware, and the original machine sequence before replacement.
Why might the controls remain inactive after installing Allen-Bradley 1336-L6/B?
Check the external control supply, neutral or return, permissive circuit, stop input, terminal mapping, board seating, connector condition, drive fault status, and programmed input assignments.
Can the existing terminal wiring be transferred directly to Allen-Bradley 1336-L6/B?
Only after the complete board identity and terminal functions are confirmed. Label every conductor, isolate all power sources, compare the official diagram, and test each control function individually.
Can Allen-Bradley 1336-L6/B be fully tested outside the drive?
Only limited inspection and component checks are practical independently. A meaningful functional test requires a compatible drive, correct control supply, safe input simulation, and monitored drive diagnostics.
What commissioning tests are important after replacing Allen-Bradley 1336-L6/B?
Test stop, start, direction, jog, speed selection, permissives, external faults, emergency-stop response, and loss-of-signal behavior before reconnecting the machine to normal production.
