The SCALANCE X-300 Industrial Ethernet switches with rugged metal housing are optimized for mounting on a standard DIN rail and the S7-300 rail. Direct wall mounting in various positions is also possible. Thanks to the S7-300 housing dimensions, the devices are suitable for integration into an automation solution with S7-300 components.

The switches have:

• a 4-pin terminal block for connecting the redundant power supply (2 x 24 V DC)
• Row of LEDs for indicating the status information (power, link status, data traffic, fault, redundancy manager, standby manager)
• A 2-pin terminal block for connecting the isolated signaling contact
• SELECT/SET key for on-site configuration of the signaling contact
• Slot for optional C-PLUG swap medium on the rear of the device for easy replacement in the event of a fault

The SCALANCE X-300 switches are available with the following port types:

• 10/100BaseTX, RJ45 connection;
