hey
im working on a project that will control 20 SSRs operating at 24 volts.
the relay board has a single input for the 24volt relay control circuit, and only require a short between the ground and the control pin for the selected relay. 24 volts will flow thought this short. i want to allow a microcontroller to run these relays i originally planned to use simple switching transistors to control each of the lines, but i wanted to use an IC as it would provide and neater circuit and less components.
Could i use the ULN2003 to contor the lines by just connecting the control pin for the the relay to the control pin on the uln chip.
Any help or ideas would be appriciated, i attached a image detailing the way i think it would be wired..
thanks
