The 1394C-SJT22-A is an Allen-Bradley servo controller with analog module functionality and a ±10 Volts DC analog interface. It is a Series C system module with features such as Smart Power, EMI filtering, and improved terminations. The 1394C-SJT22-A system can support up to four axes and work as a velocity or torque controller. It comes with the Bulletin 1201 Human-Machine Interface Module which allows automatic tuning and quick start-up. This 1394C-SJT22-A also has a SCANport interface, a continuous output current of 33.8 Amps with DC voltage, a continuous output power of 22 kW, and a three-phase power supply. The 1394C-SJT22-A has power inputs such as 24 Volts AC power, a disconnect function, a fuse block, and a 24 Volts DC power supply for motor brakes and thermal contacts.

The 1394C-SJT22-A functions on power between 324 and 528 Volts AC at 50 to 60 Hertz and an efficiency of 98%. The 1394C-SJT22-A has a capacitance of 660 µF, an inductance of 500 µH, and requires an external shunt module. The 1394C-SJT22-A has diagnostic features which include a current monitor, thermal overload detection, and a feedback signal monitor. In addition, it has status LEDs for the system and the axis modules. Electrical noise protection and improved grounding terminations are also included.
