Note : Bleeder resistance (R1) calcuation
The voltage drop across the load (R1) must be less than 40V while the
sensor is turned off.
R1 must satisfy the following three conditions.
Condition 1: R1 (Ω) ≤
Maximum input OFF voltage (= 40V AC)
Maximum sensor leakage current (A)
Condition 2: R1 (Ω) ≤
Sensor power voltage (V)
Minimum sensor load current (A)
Condition 3: P
