So Vout = Vin x R2 / (R1 + R2) ie the division ratio = R2 / (R1 + R2) When R1 = R2 the division ratio is 1/2 so. a 0-10V input will be reduced to o-5 volts. R1 and R2 can be typically 10k ohms each in this case. Much larger values can be used but they can affect the conversion accuracy. eg 100k + 100k.
