Technical Information

The ST-5444 Motion Control Module is a PACSystems RSTi 4-Channel, PWM output motion control module made by GE Fanuc. It is used for providing pulse width modulation facilities for simple motion control applications. The specifications of the field power for the module are 18 to 28.8 Volts DC of voltage range, 24 Volts DC of power supply voltage, and 50 milliamps of power dissipation at 24 Volts DC. It offers short-circuit protection diagnostic facilities, a PWM drive type, and 2500 Hertz of PWM frequency. The ST-5444 Motion Control Module does not support encoders. Its indicator LEDs help the users to easily determine the health of the channels and diagnose system failures.


The ST-5444 Motion Control Module comes with 4 channels with a positive logic type. The 4 PWM output channels are connected to Pins 0, 1, 2, and 3 of the terminal assembly, respectively. Each channel has an indicator LED to show the visible status of the channel. Another green/red LED shows the RSTi bus status. The power dissipation rating of the module is 150 milliamps at 5 Volts DC. The ST-5444 Motion Control Module has 0.5 Amps of output current per channel and 1.5 Amps of maximum inrush current. It is designed for providing integrated mechanical interlocking. The terminal assembly consists of spring clamps that accept 14 AWG wires. It supports plug and play installation and no tools are required for removal. It weighs 70 grams. It is advised to mount the module in an ATEX certified enclosure with an IP 54 protection level. This module processes pulse signals for industrial control applications.
