Allen-Bradley 1746E-H01 Drive Interface Module

The Allen-Bradley 1746E-H01 Drive Interface Module is an SLC 500 backplane card that provides a dedicated interface to Allen-Bradley 1336 drives, enabling direct control of the drive from a Rockwell Automation PLC. This module is listed under part number 1746E-H01 with a cross-reference 91007-MVI-01 and is designed for use in 1746-series SLC 500 systems to connect a 1336 drive to the 1746 backplane, translating the PLC's commands into drive-side signals. In operation, the 1746E-H01 serves as the motion-interface link within legacy automation racks, supporting a straightforward, compatible interface between the SLC 500 controller and the 1336 servo or drive unit, and it relies on the standard 1746 I/O backplane mounting. Common applications include retrofit and upgrades of older machines that require servo control or precise motion coordination via a 1336 drive, where the 1746E-H01 ensures the drive communicates correctly with the PLC without replacing the entire control system.
