No-voltage Input Signal Levels
Short-circuit level Transistor ON
• Residual voltage: 3 V max.
• Impedance when ON: 1 kΩ max.
No-contact
(The leakage current is approx. 12 mA when the
input
impedance is 0 Ω.)
Open level Transistor OFF
• Impedance when OFF: 100 kΩ min.
Contact input
Use contacts which can adequately switch 5 mA at 10 V
Note: The DC voltage must be 30 VDC max.
