2.4.3 Input Connections
Only the Encoder inputs are connected with 8-output Models.
For 16-/32-point models, the inputs are no-voltage (short-circuit or open) inputs.
■ No-voltage Inputs
Voltage-output sensors can also be connected.
• No-voltage Input Signal Levels
* Use a maximum DC power supply of 30 V.
No-contact inputs Short-circuit level for transistor ON
• Residual voltage: 2 V max.
• Impedance when ON: 1 kΩ max.
(The leakage current is approx. 2 mA
when the impedance is 0 Ω.)
Open level for transistor OFF
• Impedance when OFF: 100 kΩ min.
Contact inputs Use a contact that can adequately switch
2mA at 5 V.
Note: Operates when the transistor turns ON.
