IO-Link port pin definition
| Schematic diagram | Pin | Description |
|
1 | Power supply 24V+ (Us+) |
| 2 | Class A: I/Q: I/Q.Input (PNP) DO: Digital output (PNP) Class B: Auxiliary supply 24V+ (in IO-Link mode) I/Q: I/Q.Input (PNP) (in SIO mode) |
|
| Power supply 24V+ (Ua+) | ||
| 3 | 0 V (Us-) | |
| 4 | (1) IO-Link communication mode (2) SIO: Standard IO mode C/Q.Input (PNP) C/Q.Output (PNP/NPN) |
|
| 5 | 0 V (Ua-) |
Note:
(1) PIN 1 and PIN 3 are powered by the power supply Us, and PIN 4 is also powered by Us; when used as an output, it is not affected by a Ua power supply fault.
(2) The PIN 2 power comes from Ua; when configured as an output, the Ua power supply must remain normal.
