Overview Manuals Compatibility Analog Interface Installation Applications

Features:

  • Analog servo system module for Bulletin 1394 systems
  • 22 kW continuous output rating at 460 V AC input
  • ±10 V DC analog command interface without an included HIM
This catalog number identifies a Bulletin 1394 analog servo system module that supplies the shared DC bus for compatible axis modules.

Its complete order code specifies the 22 kW power class and the -A analog interface. The installed motor, axis module, shunt, fusing, and contactor must match official tables.

Before ordering Allen-Bradley 1394C-SJT22-A, confirm the complete order code, documented configuration, and connection requirements for the installed system.
1394C-SJT22-A Datasheet Manuals, Datasheets, Drivers, Link Documentation Note: This document is provided for technical reference. Please confirm the applicable product configuration and document revision before ordering.
  • Use 1394C-SJT22-A with compatible Bulletin 1394 axis modules whose combined load and bus capacitance remain within the official 22 kW system limits.
  • Motor, feedback, power, and brake cables must match the selected axis module and servo motor combination documented in Rockwell system selection tables.
  • Verify every installed axis module, motor feedback type, regenerative load, and external shunt arrangement before replacing or expanding the multi-axis system.
  • The -A order-code suffix identifies a ±10 V DC analog input configuration and does not include a Human Interface Module.
  • Analog velocity or torque references are commissioned through the documented 1394 analog-servo parameters and the connected axis feedback configuration.
  • Encoder, command, enable, and status wiring must follow the analog-system terminal assignments documented for this catalog configuration.
  • Use the documented branch fusing, user-supplied contactor, control power, grounding, and single-point bonding provisions for this power class.
  • This catalog configuration uses bottom power connectors and improved terminations; do not apply terminal-block arrangements from other catalog configurations to this module.
  • Confirm total axis-module capacitance, motor combinations, shunt capacity, cabinet clearance, and ventilation before energizing the completed multi-axis system.
  • The system module provides DC-bus power and analog command processing for compatible Bulletin 1394 axis modules in a multi-axis motion system.
  • Its ±10 V reference interface supports documented velocity or torque commands when connected feedback, enable, and limit signals meet official requirements.
  • The selected 22 kW power class must cover the combined axis-module load, regenerative energy, shunt duty, and cabinet thermal conditions.
Description
Allen-Bradley 1394C-SJT22-A is an analog servo system module rated for 324–528 V AC three-phase input and 22 kW output at 460 V.

The module accepts a ±10 V DC analog reference and works with compatible Bulletin 1394 axis modules. The hardware uses enhanced power terminations and EMI filtering.
