iPOS4803-SY Multi Axis System, EtherCAT Technical Reference
3.5 Digital I/O Connection
3.5.1 NPN inputs
Figure 4
Digital NPN Inputs connection for iPOS4803-SY
Remarks:
1. The inputs are compatible with NPN type outputs (input must be pulled to GND to change its default state).
2. The I/O pins are individually software selectable as either NPN inputs or outputs.
3. The length of the cables must be up to 30m, reducing the exposure to voltage surges in industrial
environment.
3.5.2 NPN outputs
Figure 5
Digital NPN Outputs connection for iPOS4803-SY
Remarks:
1. The outputs are compatible with NPN type inputs (load is tied to V
LOG
, output pulls to GND when
active and is floating when inactive).
2. The I/O pins are individually software selectable as either NPN inputs or outputs.
