About the 193X277ABG02
General Electric created the 193X277ABG02 ValuTrol signal level detector. This PCB, or printed circuit board, was made as a part of the Speedtronic 193X series. A signal level detector is a part that can alert the operator if no signal has been noticed in a specified amount of time.
Four long blue potentiometers are featured on the 193X277ABG02. The resistance of each potentiometer can be adjusted using the small knob which is featured on each component. Another name for a potentiometer is variable resistor. Two of the potentiometers are situated directly in the center of the 193X277ABG02 on either side of a transistor. The remaining two potentiometers can be found on the lower left and lower right of the of the printed circuit board. The other two transistors are sitting on either side of the 193X277ABG02 by the edges. The 193X277ABG02 also has a series of small transistors which are black and shaped like a half circle. The 193X277ABG02 has two light-emitting diodes of LEDs which are situated by the bottom edge of the PCB. The light-emitting diodes glow with a red light. Two (2) rectangular capacitors can be seen close to the top of the 193X277ABG02 on either side. The 193X277ABG02 features six (6) yellow capacitors. Three (3) of these capacitors are situated close to each other near the middle of the printed circuit board. One (1) capacitor can be found near the lower part of the 193X277ABG02. The remaining two capacitors can be seen near the upper border of the printed circuit board. The 193X277ABG02 features many brown resistors with bands in different colors. The bands come in colors like in brown, orange, red, or white.
