About the 193X277ABG01
The 193X277ABG01 is what is called a ValuTrol signal level detector. This is a type of printed circuit board or PCB. A signal level detector is a device which indicates if no signal is present for a given amount of time.
The 193X277ABG01 features four (4) long blue potentiometers. Each potentiometer contains a small knob used to adjust the potentiometer's resistance. Variable resistor is another name for a potentiometer. Two of these potentiometers are located directly in the center of the 193X277ABG01. The other two potentiometers are positioned at the bottom left and bottom right of the of the PCB. Sitting between the two potentiometers in the middle of the board is one round silver transistor. There are also two more transistors, one sitting on each side of the 193X277ABG01 by the edge. A few smaller transistors can also be seen on the 193X277ABG01. These are solid black and half-circle shaped. Two LEDs or light-emitting diodes are featured on the bottom of the 193X277ABG01. These LEDs emit a red glow. Two silver capacitors which are shaped like rectangles are sitting near the top of the 193X277ABG01 on either side. Six (6) yellow capacitors are featured on the 193X277ABG01. Three (3) of these are positioned near each other close to the center of the printed circuit board. One is sitting near the bottom of the 193X277ABG01. The last two are positioned close to the top of the PCB. The 193X277ABG01 has many resistors which are brown and have stripes of different colors. These stripes come in white, red, orange, and brown.
