Product Details

Product Description

The Allen-Bradley 1394-SJT10-C-RL is a high-performance, multi-axis digital AC servo controller and system power module under Bulletin 1394. It functions as both an efficient power conversion module and an integrated motion controller, embedding IMC S-Class (Standard GMC) functionality.

This module houses a 16-bit processor with 32K of system memory and features specialized communication options—specifically Universal Remote I/O (RIO) and AxisLink. The "RL" suffix denotes a specific revision/variant that integrates specialized terminations, advanced electromagnetic interference (EMI) filtering, and smart power management. It converts incoming 3-phase AC power into a regulated DC link voltage to supply up to four individual axis modules.

Product Advantages

• Space-Saving Modular Architecture: By combining the system power supply and the motion controller into a single "System Module," it minimizes control panel space. Up to four axis modules slide and lock onto the right side of this unit to power multiple servo motors without redundant power wiring.

• Transformerless Direct-Line Connection: Engineered to connect directly to standard 380V or 460V 3-phase power grids without requiring large, heavy, and expensive isolation transformers.

• Exceptional Efficiency (99%): Built with Insulated Gate Bipolar Transistor (IGBT) technology, the system converts power with minimal thermal losses, lowering the ambient temperature inside industrial electrical enclosures.

• Flexible Communication Backbones: Built-in Remote I/O (RIO) allows long-distance connectivity directly into legacy Allen-Bradley PLC systems, while AxisLink provides high-speed peer-to-peer data transfers between separate 1394 systems.

• Comprehensive Digital Fault Utilities: Includes real-time thermal overload tracking, phase loss detection, ground fault protection, transient voltage shielding, and clear status LEDs right on the front cover for instant diagnosis.
