DESCRIPTION

The Allen-Bradley 1394-SJT22-A is a GMC standard system module with a /-10VDC input.

The module requires an input voltage of 380/460 volts AC, three phase, an input frequency of 50/60 Hz, and a current of 28.6 amps.

It has an electrical output voltage of 530/680 V DC and a continuous power output of 17/22 kW with a peak power of 136 kW.

The continuous current output is 33.8 A and the peak current is 200.0 amps.

About the 1394-SJT22-A

The 1394-SJT22-A is a 1394 GMC Turbo system module that is part of the Allen-Bradley 1394 multi-axis motion control system.

The system module is primarily used for analogue servo systems and provides digital servo drives with a /-10VDC interface.

The system module is mounted on the far left side of the 1394 assembly, which includes the axis modules, bus connectors, and termination resistors.

Each module is mounted via a slide-lock mechanism and fasteners that are precisely aligned with each other.

The system module uses RS232/422 communication and supports the DH485 communication protocol. It can optionally be fitted with Remote I/O communication (RIO) and AxisLink communication interfaces.

When installing this system module or any other product in a 1394 system, the ambient temperature of the mounting location must be no higher than 50.0 degrees Celsius and mounted on a flat, stable vertical surface.

The mounting panel must have minimal www.ge-drive.com shock and vibration, and the environment must be free of moisture, oil, dust, and corrosive gases.

This system module is not equipped with an internal shunt resistor. An external shunt module must be installed.

Compatible shunt resistors include the 1394-SR9A, -SR9AF, -SR36A, or -SR36AF manufactured by Allen-Bradley.

The shunt module generates a significant amount of heat. Because hot air rises naturally, instruments or components that may be affected by hot air must not be mounted on top of the external shunt module.

The top clearance must be 254 mm (10.0 inches) and 155 mm (6.1 inches) on both sides, including the bottom area of the system module.

The 1394-SJT22-A module is an Allen-Bradley/Rockwell Automation GMC-Turbo system module.

The module features a 32-bit central processing unit. It also has a /-10 volt DC analogue input.

The module is powered by an AC power supply rated from 380 volts AC to 460 volts AC at 50 to 60 Hz.

The rated output power is 17 to 22 kW and the bus voltage is rated from 530 volts DC to 680 volts DC.

The 1394-DIM Drive Interface Module is recommended when interfacing the 1394-SJT22-A System Module with an external shaft drive.

The drive interface module acts as the interface between the 1394-SJT22-A module and the external shaft drive.

The Allen-Bradley 1394-SJT22-A module is part of the Allen-Bladley 1394 Modular Multi-Axis Motion Control and Drive System family.

Like other modules in this family, this module provides a direct line connection for three-phase input power, high-efficiency IGBT power conversion, and a slide-locked module-to-module connection system.

Depending on the system module used, the maximum number of axes that can be supported is 4. Axes can be connected to motors.

The Allen-Bradley 1394-SJT22-A module is fully programmable and supports configuration using Graphical Motion Control Language (GML).

In addition, the module supports standard communication options such as RS-232. RS-422. and DH-485 options.

By having the turbo option, the 1394-SJT22-a module executes programmes much faster than standard modules in the same series.
