About the 193X740AFG02
The 193X740AFG02 is a General Electric PCB manufactured for DC drive systems like the Speed Variator drive and compatible drives. The Speed Variator drive is often used to run machine tool systems, for coordinated lines, or for test stand systems. Other compatible drives are general purpose systems. The Speed Variator drive uses a DC motor, has a power and control unit, and uses a standard three-phase transformer.
A silver and blue front panel is attached to the 193X740AFG02 PCB. The board name, number, and the GE logo are written on the top edge. It has four factory-made openings located halfway down its front. One of these openings is populated by a rotary dial that is labeled “current limit.” The other openings have either been left empty or have been closed up by clips. The panel includes a rounded handle that makes it simpler for technicians to insert or extract the board from rack systems. The front panel attaches to the PCB by two screws.
The 193X740AFG02 has eight capacitors, including four polyester vinyl capacitors. The board has eight transistors. Two rotary potentiometers are located along the front edge of the board. These line up with the openings in the front panel. One connects to the rotary dial located there. The board also has many resistors and diodes. Resistors may be mounted either vertically or horizontally, but tend to be made of carbon composite material. The board also has a single varistor component. This component protects the board from surges.
