| 2 | N/C | Not connected |
| 3 | Vin- | Neg. supply voltage |
| 4 | Vin- | Neg. supply voltage |
Ethernet Interface
The SIO06 provides a 100 Mbit/s Ethernet interface via an M12 4-pin D-coded (female) connector.
Pin assignment of the Ethernet connector:
| Pin | Signal Designator | Signal Description |
|---|---|---|
| 1 | TD+ | Transmit (Diff +) |
| 2 | RD+ | Receive (Diff +) |
| 3 | TD- | Transmit (Diff -) |
| 4 | RD- | Receive (Diff -) |
Digital Inputs
The SIO06 provides 4x digital inputs via a 6-pin spring terminal connector (0...12 VDC).
Pin assignment of the digital input connector:
