• If the following maximum load resistance R
L, max
is exceeded, the load resistance R
L
must be
reduced accordingly by parallel connection of R:
f ≤ 100 Hz: R
L, max
= 47 kΩ
f ≤ 1 kHz: R
L, max
= 10 kΩ
f ≤ 10 kHz: R
L, max
= 1 kΩ
• The minimum load resistance R
L, min
is calculated as follows:
R
L, min
= (U

• open:
I ≤ 0.05 mA at U

closed:
U

= 0.2 V at I ≤ 10 mA
U

= 2 V at I ≤ 100 mA
• The output is open when the device is de-energized.
