Allen Bradley 1394-SJT22-A 22kW 1394 GMC System Module

The Allen‑Bradley 1394-SJT22-A is a 22 kW integrated GMC system module built for Rockwell 1394 multi-axis motion control platform. This unit combines the system power supply, DC bus generation and GML motion controller in one rack-mount unit, serving as the central power and control backbone for the 1394 servo rack. It accepts 380–480V three-phase AC input and converts AC power into a shared 530–680V DC bus to supply up to four 1394 series servo axis modules such as 1394-AM04 and 1394-AM07.

This motion controller executes motion programs written in GML programming language, supporting precise closed-loop position, velocity and torque control for synchronized multi-axis applications. It is equipped with standard communication interfaces including DH485, RS232 and RS422, enabling connection with PLC hosts, programming terminals and other automation devices for parameter setup, program download and real-time motion data exchange. Front panel diagnostic LEDs clearly display power status, DC bus health, controller faults, network alarms and axis communication errors, allowing maintenance engineers to quickly troubleshoot power, wiring or control failures.

Built-in protection circuits provide comprehensive safeguards including overvoltage, undervoltage, input phase loss, overcurrent and overtemperature shutdown. It is designed for continuous 24/7 operation inside industrial control cabinets, resistant to vibration, electrical noise and normal ambient temperature fluctuations. It holds UL and CE certifications and supports flexible axis combinations according to Rockwell load specifications.

Rockwell Automation has discontinued the entire 1394 GMC motion platform, so 1394-SJT22-A is only available as original surplus spare parts for legacy production lines. Automation integrators, plant maintenance teams and machine owners purchase this module for rack controller replacement, emergency repair and equipment retrofit, widely used in packaging machines, printing presses, metal forming equipment, CNC machinery and automotive assembly systems.

We supply new original Allen‑Bradley 1394-SJT22-A in stock. Every unit is inspected before shipment to verify label integrity, LED function and internal power circuit condition. Standard warranty is available, and we support worldwide express delivery via DHL, FedEx or UPS. If you need to confirm compatibility with your existing servo axis modules, firmware version and rack load configuration, send over your full rack part list for technical cross-check.
