Input Connections; Contact Input - Omron H8PS Manual

■ Input Connections

Only the Encoder inputs are connected with 8-output Models. The inputs are no-voltage (short-circuit or open) inputs.

H8PS-32@
Note: Operates when the transistor turns ON.
No-voltage Input Signal Levels
No-contact inputs Short-circuit level for transistor ON
• Residual voltage: 2 V max.
• Impedance when ON: 1 k
(The leakage current is approx. 2 mA
when the impedance is 0 .)
Open level for transistor OFF
• Impedance when OFF: 100 k
Contact inputs Use a contact that can adequately switch
2 mA at 5 V.
Note: Use a maximum DC power supply of 30 V.
■ Output Connections
Note: Internal circuit damage may result from a short circuit in the load.
