Allen-Bradley 1336T-GTB-SP1B PLC Communication Board – 1336 PLUS Series
When a communication board fails inside an Allen-Bradley 1336 PLUS drive, the consequences ripple instantly across the production floor. The drive loses its ability to receive speed commands, respond to fault resets, or report status back to the PLC — effectively rendering an entire motor control loop blind and mute. Conveyor lines stop, pumps lose coordination, and SCADA screens fill with alarms. Every minute of unplanned downtime in an industrial facility carries a measurable cost, and a missing or failed communication board is one of the most common — and most preventable — causes of that downtime.
The Allen-Bradley 1336T-GTB-SP1B is the dedicated communication option board for the 1336 PLUS family of AC variable-frequency drives. Within the 1336 PLUS series — one of Rockwell Automation’s most widely deployed drive platforms across North American and global manufacturing — this board occupies a critical position: it is the hardware interface that bridges the drive’s internal control logic to external fieldbus and serial communication networks. Cross-referenced under part numbers 1336T-LM1EN, 74103-015-51, and 74101-954-51D, this board has been specified in thousands of OEM machine designs and plant-wide retrofit projects worldwide.
