1394C-SJT10-T-RL | Allen-Bradley GMC Turbo System Module, 10 kW, 360/480V AC

The 1394C-SJT10-T-RL is a high-performance system module used in Allen-Bradley’s 1394 Servo Controller family. It is designed to control 1 to 4 motion axes, making it ideal for complex multi-axis servo applications. It operates with a SERCOS interface, allowing it to integrate advanced motion control systems. The module handles real-time data exchanges and positioning with high precision. This unit is commonly found in automation cells involving robotics, packaging, and CNC systems. It offers seamless integration with Rockwell PLCs and motion controllers for flexible system design.

The 1394C-SJT10-T-RL delivers a peak current output of 29.46 Amperes, which provides the necessary headroom for high-inertia loads. This allows the drive to momentarily exceed its continuous current rating during demanding tasks such as rapid starts or stops. Such flexibility is essential in applications where motion control must remain responsive and reliable. Exceeding continuous current briefly helps maintain performance without compromising safety. Thermal protection systems ensure the peak output is within safe operational limits. This capability makes the drive suitable for high-dynamic motion profiles.

This servo controller integrates a SERCOS digital communication interface, which allows fast, synchronized data exchange with controllers. Through this interface, it connects with PLCs such as Allen-Bradley SLC500 or ControlLogix. The SERCOS protocol ensures low-latency control, ideal for high-precision motion tasks. Additional GMC features like Remote I/O and AxisLink expand its connectivity. This enhances scalability in distributed control systems. The module’s communication design reduces wiring complexity while maintaining robust industrial performance.

Rockwell Automation has classified the 1394C-SJT10-T-RL as discontinued, with suggested migration to modern servo platforms like the Kinetix 5700 series. These newer drives support Ethernet/IP communication, faster processing, and integrated safety features. Transitioning to Kinetix drives provides better integration with Studio 5000 software and Logix PACs. Although no direct drop-in replacement exists, Rockwell provides engineering tools and support for migration planning. Customers should assess application compatibility, motor reuse, and cabling when upgrading. Using current products ensures long-term serviceability, firmware support, and spare part availability.

As of now, the 1394C-SJT10-T-RL is discontinued by Rockwell Automation and is no longer available for sale as a new product. Users are encouraged to migrate to newer platforms such as Kinetix 5700 or other CompactLogix/ControlLogix-compatible servo drives. Support and spare parts may still be accessible for some time through Allen-Bradley’s lifecycle services. Rockwell typically recommends engineering replacements for long-term support. It is advisable to check the Rockwell PCDC tool for updated compatibility and suggested alternatives. Planning an upgrade is essential to avoid future operational disruptions.
