SIEMENS SCALANCE

SIEMENS SCALANCE is a product family of industrial Ethernet switches and network infrastructure components designed for use in automation and process control environments. Developed by Siemens AG, a German multinational conglomerate with a history in industrial automation dating to 1847, the SCALANCE line addresses the need for rugged, deterministic networking in factory floors, power plants, and other industrial settings. The portfolio includes unmanaged and managed switches, routers, security modules, and wireless access points, all engineered to operate under the electrical and environmental conditions typical of industrial control cabinets. 3G Electric supplies select SCALANCE unmanaged DIN rail-mount Ethernet switches, such as the 6GK5004-1BF00-1AB2 (4-port with RJ45/SC singlemode fiber), 6GK5005-0BA00-1AB2 (5-port RJ45), and 6GK5004-1BD00-1AB2 (4-port with RJ45/SC multimode fiber). These units are rated IP20, indicating protection against solid objects larger than 12 mm but not against liquids, which is standard for indoor cabinet installation. They operate on 24V DC input voltage and support 10/100 Mbit/s network interfaces, making them suitable for legacy and current industrial Ethernet deployments. The switches are designed for DIN rail mounting, a common requirement in control panels, and feature compact form factors that conserve space. Key technical qualities include support for auto-negotiation and auto-crossover on RJ45 ports, allowing straightforward integration with existing cabling. The SC Multimode and Singlemode variants enable fiber-optic connections for extended distances or electrically noisy environments. 3G Electric supports these products by maintaining multiple SKUs with datasheets accessible for specification verification, and by providing logistics support for global shipment. The company does not modify or configure these switches; they are supplied as manufactured by Siemens. For procurement specialists and plant engineers, the SCALANCE unmanaged switches offer a straightforward, no-configuration solution for connecting sensors, actuators, and controllers in a local area network, with the reliability expected from a Siemens-branded component. The absence of management features reduces complexity and potential points of failure, which is advantageous in applications where network topology is static and does not require remote monitoring or VLAN segmentation. 3G Electric's inventory covers common port counts and media types, enabling buyers to select the appropriate variant based on distance requirements and existing fiber infrastructure.

Frequently asked questions

Common questions about SIEMENS SCALANCE from 3G Electric.

What is the difference between the SIEMENS SCALANCE unmanaged switches with SC Singlemode and SC Multimode fiber ports?

The SC Singlemode variant (e.g., 6GK5004-1BF00-1AB2) uses a single strand of fiber to transmit data over longer distances, typically up to 10 km or more, depending on the transceiver. The SC Multimode variant (e.g., 6GK5004-1BD00-1AB2) uses a larger core fiber that supports shorter distances, usually up to 2 km, but is generally less expensive. Both operate at 10/100 Mbit/s and are unmanaged, meaning they require no configuration. Choose Singlemode for long runs between buildings or across large facilities; choose Multimode for shorter runs within a plant or control room.

Can the SIEMENS SCALANCE unmanaged switches be powered by a standard 24V DC industrial power supply?

Yes, these switches accept a maximum input voltage of 24V DC, which is standard in industrial control panels. They are designed to be powered by a regulated DC power supply, such as a Siemens SITOP or equivalent. The switches do not include a power supply; you must provide a 24V DC source. Polarity protection is typically built in, but always verify the wiring diagram in the datasheet. The power consumption is low, typically under 5 W for unmanaged models.

What is the IP20 rating on SIEMENS SCALANCE switches, and where can they be installed?

IP20 means the switch is protected against solid objects larger than 12 mm (e.g., fingers or tools) but has no protection against water ingress. This rating is suitable for installation inside a control cabinet or enclosure that provides additional environmental protection. Do not install IP20-rated switches in wet, dusty, or outdoor locations without a proper enclosure. For harsher environments, Siemens offers SCALANCE models with higher IP ratings, but those are not covered in this product range.

Do the SIEMENS SCALANCE unmanaged switches support auto-negotiation and auto-MDI/MDIX?

Yes, the RJ45 ports on these unmanaged switches support auto-negotiation for speed (10/100 Mbit/s) and duplex mode, as well as auto-crossover (auto-MDI/MDIX). This allows you to use straight-through or crossover cables without concern, simplifying installation. The fiber ports (SC) operate at fixed 100 Mbit/s full duplex and do not require negotiation. No configuration is needed for these features.

What is the typical lead time for SIEMENS SCALANCE switches ordered through 3G Electric?

Lead times depend on stock availability at the time of order. 3G Electric maintains inventory of common SKUs like the 6GK5004-1BF00-1AB2, 6GK5005-0BA00-1AB2, and 6GK5004-1BD00-1AB2. For in-stock items, orders are typically processed within 1-2 business days, with shipping times varying by destination. For out-of-stock or special-order variants, lead times may extend to several weeks. Contact 3G Electric for current stock status and estimated delivery.
