Short-circuit level (transistor ON)
• Residual voltage: 3 V max.
• Impedance when ON: 1 kΩ max.
(The leakage current is approx. 12 mA when the 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.
Applicable Two-wire Sensor
• Leakage current: 1.5 mA max.
• Switching capacity: 5 mA min.
• Residual voltage: 3 VDC max.
• Operating voltage: 10 VDC
