What type of device is this and what does it do in an industrial network?

It is an unmanaged Industrial Ethernet (IE) switch used to connect multiple Ethernet-capable devices in a small industrial network. It forwards traffic automatically (no configuration required) and is commonly used to build simple line or star network structures.

How many Ethernet ports does it have?

It provides 8 x 10/100 Mbit/s RJ45 copper ports for connecting typical Industrial Ethernet devices.

Does it include fibre optic connections?

Yes. In addition to the copper ports, it has 2 x 100 Mbit/s multimode fibre optic ports using ST/BFOC connectors (100Base-FX).

What network topologies is it typically used for?

It is designed for small line and star topologies. This makes it suitable for machine cells, small process skids, and local control panels where straightforward Ethernet distribution is needed.

Is any configuration required before use?

No. As an unmanaged switch, it operates out of the box—connect power and network cables and it will start switching traffic automatically.

What supply voltage does it require?

It uses 24 V AC/DC supply. The permitted input range is 19.2 to 28.8 V.

Does it have redundant power inputs?

Yes. It includes a connection for redundant voltage supply, allowing two independent 24 V feeds to be connected for improved availability.

What is the typical power consumption?

Power loss is specified as 7.2 W at 24 V DC, and the maximum current consumption is 0.3 A.

Is there built-in protection on the power input?

Yes. Fusing at the power supply input is included; the fuse protection type is specified as 0.6 A / 60 V.

What are the permitted operating environmental conditions?

Permitted ambient temperature during operation is 0 to 60 °C. Relative humidity during operation is up to 95% at 25 °C, non-condensing.

What is the IP rating and what does that mean for installation?

It is rated IP20, meaning it is intended for installation inside a cabinet or enclosure where it is protected from dust ingress and water exposure.

How is it mounted in a control cabinet?

It is designed for 35 mm DIN rail (top-hat) mounting. Wall mounting is not specified for this model.

What are the physical dimensions and weight?

The unit is compact: 80 mm (W) x 117 mm (H) x 109 mm (D) with a net weight of approximately 0.34 kg.

Does it provide traffic prioritisation features?

Yes. It includes CoS (Class of Service) capability to help prioritise traffic on the network, even though the device is not managed.

Is it suitable for PROFINET networks?

Yes. It is specified as PROFINET conformity class A, which is commonly used for basic PROFINET communication in industrial environments.

Can it be used in PRP networks?

Yes. It is specified for operation in a Parallel Redundancy Protocol (PRP) network. (PRP Redundant Network Access (RNA) is not specified.) For reference, this variant is commonly identified as Siemens 6GK5108-2BB00-2AB2.
