This circuit is used for CDE TR-44 antenna control, which uses a low voltage AC motor with a potentiometer display. The circuit eliminates the need to control the position until the antenna reaches the desired orientation. Using a 12VDC 1000Ω 1A relay, the TISN7274IL op amp U1 and a 360° rotary potentiometer R7 operating under 14V regulation of the original control.
The CDE TR-44 antenna control circuit is a sophisticated system that utilizes a low voltage AC motor along with a potentiometer display to effortlessly adjust the antenna's orientation. This circuit is designed to streamline the process of antenna positioning, eliminating the need for constant manual adjustments until the desired orientation is achieved. The core of this system lies in its precision and reliability, which is achieved through the use of a 12VDC 1000Ω 1A relay, the TISN7274IL operational amplifier U1, and a 360° rotary potentiometer R7.
The 12VDC 1000Ω 1A relay serves as the switching mechanism, allowing the circuit to precisely control the flow of power to the AC motor. This ensures that the antenna rotates smoothly and precisely to the desired position. The TISN7274IL operational amplifier U1 plays a crucial role in amplifying and conditioning the signals within the circuit. It receives input from the potentiometer R7, which represents the desired antenna orientation, and then adjusts the output accordingly to drive the motor.
The 360° rotary potentiometer R7 is the user interface for adjusting the antenna's position. Operating under 14V regulation of the original control system, it provides a continuous range of resistance values that correspond to the desired antenna orientation. By turning the potentiometer, the user can incrementally adjust the antenna's position, while the operational amplifier U1 and relay work together to smoothly and precisely move the antenna to the desired orientation.
The integration of these components results in a highly reliable and efficient antenna control system. The user simply needs to turn the potentiometer to the desired position, and the circuit will take care of the rest. This eliminates the need for constant monitoring and manual adjustments, saving time and effort while ensuring precise antenna positioning. The use of a low voltage AC motor also ensures quiet and smooth operation, minimizing any potential interference with other electronic equipment in the vicinity.
