Description: This is a circuit for alternative sources selection. It combines mechanical selection using a rotating switch S1, the electronic drive of the relays RL 1-10 and also the optical indication of the selection by the Display DSP1. The function is based on the connection of the mechanical selections into 4 Bit (BCD) code. It is managed by the proper polarization of the diodes D1-10 and simultaneous convention into decimal output by IC2 which is a BCD to decimal decoder. The monitor is driven by the IC1, which is a BCD to 7-segment Latch/ decoder/ driver. We can made a lot of combinations and selections on the circuit. For instance, we may add Led's in parallel with the RL1-10.
The circuit is designed to facilitate the selection of alternative sources using both mechanical and electronic components. The mechanical selection is achieved through a rotary switch (S1), which allows the user to choose among ten different options. Each position of the switch corresponds to a unique state represented in Binary-Coded Decimal (BCD) format.
The electronic control of the relays (RL1 to RL10) is handled by a combination of diodes (D1 to D10) that ensure proper signal routing and isolation between different paths. The BCD input from the switch is processed by the IC2, which is a BCD to decimal decoder (CD4028). This IC translates the BCD input into a corresponding decimal output, activating the appropriate relay based on the selected input.
The display of the selected option is managed by IC1, a BCD to 7-segment latch/decoder/driver (CD4511). This component takes the BCD output from IC2 and drives a common cathode 7-segment display (DSP1), providing a visual representation of the selected source.
The circuit includes a variety of resistors (R1 to R12) and capacitors (C1, C2) that help in biasing and stabilizing the circuit. The relays (RL1 to RL10) can operate at either 6V or 12V, allowing for flexibility in power supply choices. Additionally, there is potential for further enhancements, such as adding LEDs in parallel with the relays to provide additional visual feedback for the selected options. This circuit design allows for versatile combinations and selections, making it suitable for various applications where source selection is required.
