41 11 pin relay diagram
The components used are PT100 sensor, arduino uno, MAX31865 driver, solid state relay (SSR), LCDi2C, electric stove, heater, analog joystick. This tool works, when the analog joystick is to adjust, it sets the upper limit number and lower limit number. After setting the upper and lower limits, Arduino processes it. (Pin #24 is still the igntion input, marked 'tach' on the relay board.) The ignition control signal from MegaSquirt-II on DB37 pin#36 corresponds to the relay board pin S5 of the 20 position terminal strip. If you use a stepper motor IAC with the relay board, and have connected the wires for the IAC to DB37 pins 25, 27, 29, and 31, then: For example, if you remove the relay from the fuse box, you'll notice that it has a weird-looking diagram along with some numbers. Those numbers or pins control different things in your relay. For example, a 4-pin relay uses pin 85, 86, 30, and 87. Notice that they are spawned across the relay for the sake of convenienc...
