7 ELECTRONICS AND INTERFACINGThis short introduction to the electronics, most often needed by digital I/O boardusers, covers a few key concepts.IMPORT

Of course, a pull-down resistor accomplishes the same task except that the line ispulled low when the board is reset and the output has more than enou

SSRs. If you have only a few outputs to control, you may also wish to consider theDR-OAC or DR-ODC, single point, DIN mountable SSRs. The high current

For a given attenuation, pick a handyresistor and call it R2, then use thisformula to calculate R1.R1 = (A−1) x R2Digital inputs often require voltage
