About the DS3820RPSA
The DS3820RPSA is a servo module designed by General Electric for use with the Mark IV Speedtronic system. The MKIV was the first Speedtronic system to offer triple modular redundant control where three controller boards all offer off data that is voted before it is used for control decisions.
The DS3820RPSA component is designed as a circuit board mounted into a metal frame. This frame has two short sides and two taller sides. The two taller sides end top and bottom in top hat flanges. The bottom flange includes cutouts for screw mounts while the top flange is drilled in several locations.
The DS3820RPSA circuit board includes a number of stab-on connectors with surface wired connectors. It has multiple high-voltage capacitors, as well as resistors and diodes. The board has ten connectors located on its surface to allow for connections to other components.
Servos are used to communicate lower power command signals into higher voltage and current. They can sometimes regulate and coordinate torque, speed, position, etc.
For additional information about the DS3820RPSA module, please refer to original documentation from General Electric including datasheets and user guides. Product manuals will provide detailed information regarding the installation and maintenance of this product.
The Mark IV distributed control functions are considered to be a distinct improvement over previous Speedtronic systems. Microprocessor control within the system allowed for logging, remote control systems, condition monitoring, and temperature control.
