Resistor relay
WebOct 13, 2010 · No just a single 120 Ohm resistor in series with each relay. Also your relays are 5 volt with a minimum pull in of 3.75 V so you figure your relay coil as 5 volt and not the minimum pull in. Also, I thought about what ronv mentioned. Why not use 12 volt relay coils? Less current and less waste. Ron

WebDec 20, 2012 · The following relay economy circuits reduce coil power significantly by simply adding a series resistor. As soon as the relay picks up, the coil voltage is reduced … WebBy adding a 120-ohm resistor at the end of an RS485 transmission line, the signal will be dampened by the resistor instead of reflected into the bus. If the value of the resistor does not match the characteristic impedance of the cable, reflection may occur. In most RS485 configurations, two termination resistors are used.
WebAdding a pull-up at the collector of Q1 will just increase the amount of current drawn when Q1 is on, increasing heat dissipation. The relay will still be energized during start up, …
