The 74101-371-52 REV.04 is a drive control printed circuit board designed as a critical interface between the power stage and the logic/control stage in industrial AC drive systems. As an intermediate control layer, it is responsible for distributing command signals, collecting feedback, and maintaining electrical isolation between sensitive control electronics and high-power components.
The 74101-371-52 REV.04 provides the electrical interconnect infrastructure required for reliable communication between multiple sub-components in the drive system. This includes connector interfaces, feedback paths, and protection-related circuitry to support monitoring and fault management. Therefore, this board plays a crucial role in ensuring system robustness, maintainability, and compatibility between different drive platform versions.
The 74101-371-52 REV.04 Allen Bradley AC Drive Board may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

From an operational perspective, the 74101-371-52 REV.04 acts as a signal processing and distribution center. Input control commands from the drive controller are processed by this circuit board and routed to the corresponding subsystems; simultaneously, feedback signals from sensors and protection circuits are also collected and sent back to the control logic. Through coordinated signal routing, isolation, and processing, this circuit board achieves closed-loop control of the drive system, thereby ensuring precise motor control, fault detection, and stable system performance.
Allen-Bradley 1336 Series Drives: The most common application is as a replacement control board for the 1336 series (including 1336 PLUS, 1336 IMPACT, and 1336 FORCE).
High-Power Motor Control: Designed for 200 hp (HP) drives to manage large three-phase induction motors in heavy industrial environments.
Industrial Automation Systems: Can be used as a PLC peripheral module or interface to help simplify automation processes by controlling motor speed and torque.
Traction and Heavy Machinery: Used in systems requiring precise adaptive control of position and speed, such as cranes, lifts, or large manufacturing conveyor applications.
