Resistors and inputs connected in parallel;
Parallel resistance Rp: FX
2NC
= 15k
Ω
. If resistance Rp is less than the stated value, then add
Rb. See equation 1 for Rb calculation.
Alternatively; Current leakage: FX
2NC
= 1.5mA. If the current leakage is greater than the stated
value, then add Rb. See equation 2 for Rb calculation.
