relay driver using uln2803 to switch on the lamp

[BISH]

hi all,

i want "a relay driver circuit using uln2803 to switch on the lamp" in proteus

 

[Tahmid]

Connect input drive signal to ULN2803 input pin. Connect lamp between the corresponding output pin and +V. Connect pin 10 (COM) to +V. In Proteus, the common emitter pin of ULN2803 is hidden and is connected to ground.

By the way, for driving a single lamp, you can just use a transistor. You don't need to use ULN2803.

Hope this helps.
Tahmid.

This has already been discussed in several threads in the past

ELN2003 and 2803 use are functionally the same with some small differences in electrical characteristics
