SCALANCE

SCALANCE is a family of industrial Ethernet networking components developed by Siemens for use in automation environments. The line includes switches, routers, and access points designed to operate in control cabinets and on plant floors, where vibration, temperature variation, and electrical noise are common. SCALANCE products are typically mounted on DIN rails and use standard RJ45 connectivity, with port counts and speed grades that scale from small entry-level unmanaged switches to managed devices with redundancy functions. The portfolio is built around the practical requirements of industrial networks: deterministic data transfer, diagnostic visibility, and mechanical robustness. Many models carry IP20 or IP30 ratings, indicating protection against solid objects and, in the case of IP30, limited ingress of dust and water spray. Operating voltages are commonly 24 V DC, matching the control power available in most automation panels. Managed variants offer features such as integrated redundancy managers, error signaling contacts, and select/set buttons for local configuration. Unmanaged variants provide simple plug-and-play connectivity for devices that do not require network segmentation or monitoring. Speeds range from 10/100 Mbit/s for legacy and low-bandwidth applications to 10/100/1000 Mbit/s for higher-throughput segments. LED diagnostics are present across most models, giving maintenance personnel a quick visual indication of link status, data activity, and fault conditions without needing a laptop or software tool. 3G Electric supplies the SCALANCE line as part of its industrial equipment catalog, offering multiple SKUs that cover different port counts, management capabilities, and environmental ratings. The switches are available for global shipment, and 3G Electric provides logistics support and quotation services for procurement teams specifying SCALANCE components in new installations or as replacements in existing networks. The product range includes unmanaged switches with 4, 5, or 8 RJ45 ports at 10/100 Mbit/s, managed switches with 7, 8, 10, or 16 RJ45 ports at speeds up to 10/100/1000 Mbit/s, and models with integrated redundancy managers for ring topologies. IP20 and IP30 enclosures are both represented, allowing selection based on the level of environmental protection required by the installation site. For plant engineers and maintenance managers, the key selection criteria are port count, speed, management level, and ingress protection. SCALANCE switches are typically used to connect programmable logic controllers, human-machine interfaces, drives, and other Ethernet-enabled devices within a cell or line. The managed models support network diagnostics and redundancy, which can reduce downtime in continuous-process applications. The unmanaged models are suited to simple star or linear topologies where configuration is not needed. 3G Electric maintains inventory and handles order fulfillment for these SKUs, providing a single point of contact for buyers who need SCALANCE switches alongside other industrial components. The catalog includes part numbers that correspond to specific port configurations and feature sets, and 3G Electric can assist with identifying the correct model based on the technical requirements of the application.

Frequently asked questions

Common questions about SCALANCE from 3G Electric.

What is the difference between managed and unmanaged SCALANCE DIN rail-mount Ethernet switches?

Managed SCALANCE switches support configuration and network management functions such as redundancy, diagnostics, and error signaling. They typically include features like an integrated redundancy manager or a select/set button for local adjustments. Unmanaged SCALANCE switches operate without configuration; they simply forward Ethernet frames between connected devices. Unmanaged models are suitable for basic connectivity where network segmentation or monitoring is not required. Managed models are used when network resilience, remote diagnostics, or controlled data paths are needed. Both types are available in DIN rail-mount form factors with RJ45 ports and LED diagnostics.

What IP ratings are available for SCALANCE industrial Ethernet switches?

SCALANCE DIN rail-mount Ethernet switches are available with IP20 and IP30 ratings. IP20 indicates protection against solid objects larger than 12.5 mm, such as fingers, and no protection against water. IP30 indicates protection against solid objects larger than 2.5 mm, such as tools and wires, and also no water protection. These ratings are typical for equipment installed inside control cabinets or protected enclosures. The specific rating depends on the model; for example, some unmanaged switches with 4 or 8 ports are IP20, while certain managed and unmanaged models with 5, 7, 8, or 10 ports are IP30.

What network speeds do SCALANCE DIN rail-mount Ethernet switches support?

SCALANCE DIN rail-mount Ethernet switches in the 3G Electric catalog support 10/100 Mbit/s or 10/100/1000 Mbit/s network interfaces. The 10/100 Mbit/s models are suitable for legacy devices, low-bandwidth control traffic, and applications where gigabit speeds are not required. The 10/100/1000 Mbit/s models support higher throughput for data-intensive devices, larger network segments, or future capacity needs. Both speed classes use standard RJ45 ports. The appropriate speed depends on the connected devices and the overall network design. Managed and unmanaged variants exist in both speed ranges.

How many ports are available on SCALANCE DIN rail-mount Ethernet switches?

SCALANCE DIN rail-mount Ethernet switches are available with port counts ranging from 4 to 16 RJ45 ports. Unmanaged models include 4, 5, and 8 port versions. Managed models include 7, 8, 10, and 16 port versions. The port count determines how many Ethernet devices can be connected directly to the switch. For small cells with a few devices, a 4 or 5 port unmanaged switch may be sufficient. For larger network segments requiring management and redundancy, higher port count managed switches are used. All ports are RJ45 and support standard Ethernet cabling.

What is the Integrated Redundancy Manager on SCALANCE managed switches?

The Integrated Redundancy Manager is a feature found on certain managed SCALANCE DIN rail-mount Ethernet switches. It enables the switch to participate in a redundant ring topology, where network traffic can be rerouted if a cable or segment fails. This helps maintain network availability in industrial applications where downtime is costly. The redundancy manager typically works in conjunction with other switches that support the same redundancy protocol. Models with this feature include managed switches with 7, 8, or 10 RJ45 ports at 10/100/1000 Mbit/s. Configuration is done through the switch management interface.

What input voltage do SCALANCE DIN rail-mount Ethernet switches require?

SCALANCE DIN rail-mount Ethernet switches in the 3G Electric catalog operate on 24 V DC input. This is a common control voltage in industrial automation panels, allowing the switches to be powered from the same supply as other control components. The 24 V DC input is specified for unmanaged models with 4, 5, and 8 ports, and is typical for the managed models as well. Users should verify the exact voltage range and power consumption for the specific model from the technical datasheet. Proper polarity and fusing should be observed during installation.
