IO-Link hubs (Port Multipliers) expand a single IO-Link master port into multiple IO-Link device ports. They use M12 connectors for both upstream master connection and downstream device connections.
| Pin | Name | Function | Type |

| 1 | L+ | 24V supply | PWR |
| 2 | NC | Not connected | I/O |
| 3 | L- | Ground | GND |
| 4 | C/Q | IO-Link communication | BUS |
