BCD to 7seg Decoder (0-9) using relays.
This is a 7-segment decoder circuit capable of displaying 0 to 9.
This circuit is intended to be used for clocks.
It is optimized to use only 11 contacts.
Commercially available 7-segment LEDs cannot be used because they have a common anode or cathode.
Also, depending on the seg, non-polarized displays or rectifier circuits must be added for proper operation.
