Product Description:
The PRS-2391C Servo Drive Board is designed for servo system applications requiring precise motor control. It features a microcontroller and reliable discrete components. The board supports motion control through embedded firmware logic.
The PRS-2391C servo drive board is built around the Motorola 68AA050FXR00 microcontroller. This processor supports both 16 and 32 bit operations. It is mounted in a surface mount format for reduced footprint and improved reliability. The board includes two ADTHE07-C ROM/EPROM chips. One of these chips is socketed in DIP format for easy replacement. These ROMs store motion control firmware or other operational logic. A system oscillator provides a stable clock source for the microcontroller and logic operations. The board features a Sanyo Denki XK-1440 electromechanical relay. This relay operates at either 12 V or 24 V DC and is used for high power load switching. Capacitors used on the board include ceramic disc types ranging from 0.01 µF to 0.1 µF. Electrolytic capacitors are included for filtering and power regulation purposes. Standard 1/4 watt through hole resistors are used across the board. Additionally, multi turn potentiometers are provided for calibration and circuit trimming.
Communication interfaces of the PRS-2391C servo drive board include a 15 pin D Sub connector that supports RS-232 or RS-422 standards. The board also includes multiple edge connectors with 20 to 30 pins each. These connectors support power input, signal I/O or data bus communication. The relay indicates that the board operates on a 12 – 24 V DC control supply. Custom logic is supported by DIP format ICs located in the IC20 to IC30 range. These chips function as decoders, buffers, latches, or analog switches. The board ensures consistent performance in industrial or motion control environments.
