SIEMENS SCALANCE

About SIEMENS SCALANCE

Siemens SCALANCE is a family of industrial networking components designed for use in automation environments. The line includes switches, routers, and access points intended for deployment in control cabinets, on machines, and across plant networks. SCALANCE products are engineered to operate in electrically noisy and thermally demanding conditions typical of manufacturing and process industries. The portfolio spans unmanaged switches for simple connectivity, managed switches for network segmentation and diagnostics, and wireless components for mobile or hard-to-wire assets. Many models support common industrial protocols and are configured for DIN rail mounting, 24 V DC power, and protection ratings appropriate to their installation location. 3G Electric supplies Siemens SCALANCE products globally, with a focus on DIN rail-mount Ethernet switches. The current inventory includes unmanaged switches with 4 or 5 ports, offering combinations of RJ45, SC multimode, and SC singlemode interfaces. These units operate at 10/100 Mbit/s and carry an IP20 rating, making them suitable for use inside enclosures or control rooms. The switches accept a maximum input voltage of 24 V DC and are designed for straightforward installation on standard DIN rails. This makes them applicable to machine-level networking, control panel integration, and small-cell aggregation where managed features are not required. For technical buyers, SCALANCE switches are specified by port count, port type, network speed, IP rating, and input voltage. The unmanaged models in the 3G Electric catalog are fixed-configuration devices, meaning no configuration software or management interface is needed. They forward Ethernet frames automatically and support auto-negotiation and auto-crossover on RJ45 ports, simplifying cabling and commissioning. The inclusion of fiber optic ports—both multimode and singlemode—allows for longer cable runs and electrical isolation between network segments, which is common in industrial settings where ground loops or electromagnetic interference can affect copper cabling. The IP20 rating indicates protection against solid objects larger than 12.5 mm but no protection against water, so these switches must be installed in a suitable enclosure or controlled environment. The 24 V DC input aligns with typical industrial power supplies used in control systems. 3G Electric supports the SCALANCE line by maintaining stock of multiple SKUs and providing logistics coordination for global shipments. The company serves plant engineers, maintenance managers, and procurement specialists who need to source specific part numbers for new installations, replacements, or spares. Because the product range includes variations in port type and count, buyers can select the model that matches their existing network infrastructure, whether that uses copper only or a mix of copper and fiber. 3G Electric does not manufacture SCALANCE products; it distributes them as part of a broader portfolio of industrial equipment. The focus is on supplying the correct part number with documentation and delivery support, rather than providing network design or integration services. For applications requiring managed functionality, higher port densities, or different protection ratings, other SCALANCE models exist outside the current 3G Electric listing. The unmanaged DIN rail switches described here represent a subset of the SCALANCE family, aimed at basic connectivity tasks where reliability and ease of use are priorities. Technical specifications such as 10/100 Mbit/s speed, 24 V DC input, and IP20 enclosure rating are consistent across the listed SKUs, with the primary differences being port count and media type. This allows buyers to standardize on a familiar form factor and power scheme while choosing the interface mix that fits their cabling plan. 3G Electric provides these products with the expectation that they will be integrated into larger automation systems, often alongside PLCs, HMIs, and drives. The switches are passive in the sense that they do not require configuration, but they must be correctly powered and connected to function. Proper installation involves mounting on a DIN rail, connecting the 24 V DC power supply with correct polarity, and using appropriate cables for RJ45 or fiber optic connections. For fiber ports, the choice between multimode and singlemode depends on the distance and existing fiber plant. Multimode is typically used for shorter runs within a building or between cabinets, while singlemode supports longer distances. Both types are available in the 3G Electric inventory. The SCALANCE brand is part of Siemens’ industrial automation offering, which includes a wide range of control and networking products. The SCALANCE name is associated with industrial Ethernet infrastructure, and the products are commonly found in manufacturing, process, and infrastructure applications. 3G Electric’s role is to make these specific unmanaged switch models available to buyers who need them, with an emphasis on accurate part identification and global shipping. The company does not publish pricing on its website; instead, it invites requests for quotes. This approach allows for handling of varying quantities, shipping destinations, and any special documentation requirements. For procurement specialists, the key details to confirm when ordering are the SKU, port configuration, and any specific labeling or packaging needs. The products are supplied as individual units, and 3G Electric can coordinate logistics to many regions. In summary, Siemens SCALANCE unmanaged DIN rail Ethernet switches provide basic network connectivity for industrial environments. The models available through 3G Electric include 4-port and 5-port versions with RJ45 and fiber optic options, all operating at 10/100 Mbit/s with IP20 protection and 24 V DC input. 3G Electric supplies these products globally, supporting buyers who need specific part numbers for their automation and control systems.
