Use this industrial hub from Siemens to connect your network devices on a LAN. Simply run a cable from each of its two RJ45 ports to your terminal points to send data at 10 or 100Mbit/s via Ethernet. For speedy setup in standard cabinets, the unit snaps directly onto a 35mm DIN rail. It's a hardy component that withstands temperatures from 0°C to +40°C in vertical installations and up to +60°C when horizontal. You'll often find this product used in energy and robotics applications.

• Supply voltage of 24V DC for wide compatibility
• Supports data transfer rates of 9.6 and 12Mbit/s on PROFIBUS for versatility
• Weight of 600g keeps your DIN rail free of unnecessary pressure
• Low maximum current consumption of 300mA saves energy
• Small size of 100 (W) x 117 (H) x 74mm (D) for installation in compact systems

It has an IP20 rating, which means that it's touch-proof and protected against tools larger than 12mm, so you can carry out maintenance without risking electric shocks.
