Short-circuit level
Transistor ON
Residual voltage: 3V max.
Impedance when ON: 1KΩ min.
(the leakage current is 5 to 20 mA
when the impedance is 0 Ω )
Open level
Transistor OFF
Impedance when OFF: 100KΩ min.
Contact input
Use contact which can adequately
switch 5 mA at 0V.
The DC voltage must be 30VDC.
