Connection

Typical connection


The Railduino module requires a 12–24 V DC power supply for operation.

To fully utilize the module's functionality, connect it to a LAN network. An optional RS485 connection is also available.

When integrated with a supervisory system (e.g., Loxone), communication can be established in two ways (see the picture above):
- A - LAN
- B - RS485

The RS485 bus can be terminated using the integrated terminator.
Refer to the DIP switch settings for configuration details - see DIP switch settings
