need help from u guys, please. A million thanks if can help. =( i have problems of this circuit layout. 1) what's the purpose for dotted line between pin 12 to 11? But the ic is ULN2003. Is the dotted line meant to be repeated the circuit as in pin 10? 2) Is the relay RL7 example is included with the switch (S7)? 3) Do relays have ohms reading, example 200ohm, 12V? I dont understand well, sorry. 4) What is the meaning of N and PH bottom of the image?
