About the 193X242ABG03

• The 193X242ABG03 is a Tachometer monitor board manufactured by GE.
• It measures the rotation speed (RPM) of DC motors.
• This PCB component is designed for use in GE systems with DC motors, including:
  • Speed Variator Drive System: An adjustable speed, closed-loop, bidirectional system used for machine tool control, coordinated lines, or test stand systems.
  • SCR Drive System: A unidirectional, adjustable acceleration, and adjustable speed, closed-loop system, also used for coordinated lines and machine tool control. It is considered a general-purpose drive.
• The board features a front faceplate with:
  • A single curved handle for easy insertion and removal during maintenance.
  • Markings indicating its ID number, use, and the GE logo.
  • Four round openings, one of which is plugged.
  • Two openings that provide access to trim potentiometers located directly behind them, with their functions marked on the faceplate.

The 193X242ABG03 is populated by several transistors (two types), along with capacitors typically made of polyester vinyl and resistors made of carbon composite material. Components may be mounted horizontally or vertically. More information on the board and its components can be found through GE publications like manuals and user guides.
