The Allen Bradley 1394-SJT05-E is a sophisticated servo system module characterized by its analog control approach. With compatibility for a CNC interface, this module can be integrated seamlessly into machinery for enhanced automation. It lacks a human-machine interface, focusing instead on direct analog command input, which utilizes a ±10 V DC signal for operational feedback.

Designed for robust performance, the module operates using a rated AC input voltage of 324 to 528 V across three-phase power systems, functioning effectively at 50 or 60 Hz. The standard operation draws an AC input current of 6.5 A (RMS), and it can momentarily handle peak inrush currents surging to 975 A. The design incorporates a line loss ride-through feature that allows it to sustain operations for 20 ms during transient power interruptions, ensuring reliability.

On the DC side, it generates an output voltage between 530 and 680 V DC, which is practical for demanding applications. Its continuous power output capabilities range from 4 to 5 kW, with a peak potential output reaching up to 28 kW. This module features a bus capacitance of 220 µF, complemented by an internal inductance of 1000 µH, enabling stability and efficiency in performance. The 1394-SJT05-E is well-constructed for applications requiring precision and power in servo control.
