1394-SJT22-A

The 1394-SJT22-A is 1394 GMC Turbo System Module that is part of Allen-Bradley’s 1394 Multi Axis Motion control system. This system module is basically used in analog servo system and provides a digital servo drive with +/- 10VDC interface.

System modules are installed at the leftmost of a 1394 assembly which includes axis module, bus connector and terminating resistor. Each module is installed through a slide-lock mechanism and fasteners that align exactly with each other.

This system module is built with an RS232 / 422 communication and supports DH485 communication protocol. It may be optionally installed with a Remote I/O communication (RIO) and AxisLink communication interfaces.

When mounting this system module or any other product within the 1394 systems, the installation location’s ambient temperature must not be greater than 50.0 Deg. Celsius and mounted on a flat, stable vertical surface. The installation panel must have minimal shock and vibration while the environment must be clear with moisture, oil, dust and corrosive gasses.

This system module does not come with an internal shunt resistor. External shunt module must be mounted. The compatible shunt resistors include Allen-Bradley manufactured 1394-SR9A, -SR9AF, -SR36A or -SR36AF. The shunt module generates a significant amount of heat. As warm air naturally goes up, instruments or components that may be affected by warm air must not be mounted on top of the external shunt module. The Top clearance must measure 254 mm (10.0 inches), 155 mm (6.1 inches) for both sides including bottom area of the system module. The 1394-SJT22-A module is a GMC Turbo system module from Allen-Bradley/Rockwell Automation. The module features a 32-bit central processing unit. Also, it features a +/-10 Volts DC analog input. The module is powered by an AC power supply with a voltage rating of between 380 Volts AC and 460 Volts AC at a frequency of 50 to 60 Hertz. The nominal power output of 17 to 22 kilowatts while its bus voltage is rated at 530 Volts DC to 680 Volts DC. When the 1394-SJT22-A system module is being interfaced with an external axis drive, the 1394-DIM drive interface module is recommended. The drive interface module acts as an interface between the 1394-SJT22-A module and the external axis drive. The Allen-Bradley 1394-SJT22-A module belongs to the Allen-Bradley 1394 modular multi-axis motion control and drive system family. The module, like others in this family, provides a direct connection line for 3-phase input power, efficient IGBT power conversion, and a slide-and-lock module-to-module connection system. Depending on the system module that is used, the maximum of axis that can be supported is 4 axis. where axis can be interfaced to a motor. The Allen-Bradley 1394-SJT22-A module is completely programmable and supports configuration with the graphical motion control language (GML). Additionally, the module supports standard communication options such as the RS-232, RS-422, and DH-485 options. By having a turbo option, the 1394-SJT22-A module executes programs much faster compared to standard modules in the same family.
