  Standard 35mm DIN rail mounting with minimal footprint (40mm width) fits into space-constrained control cabinets. Redundant power input options (24V DC) and LED diagnostics per port simplify troubleshooting and maintenance.
• Electromagnetic Immunity
  Conforms to EN 61000-6-2 (industrial immunity) and EN 55011 Class A (emissions), protecting against electrical noise from VFDs, motors, welding equipment, and high-voltage switchgear—critical for stable PLC-to-HMI and SCADA communications.
• Long Service Life & Low Maintenance
  Fanless convection cooling design eliminates mechanical wear, MTBF exceeds 10 years under rated conditions. Conformal coating option available for corrosive atmospheres (chemical plants, offshore platforms).
• Seamless Siemens Ecosystem Integration
  Native compatibility with SIMATIC controllers, WinCC SCADA, TIA Portal engineering software, and PROFINET networks. Supports IEEE 802.3 Ethernet standards for interoperability with third-party devices (Allen-Bradley, Schneider, Omron, etc.).

Typical Application Scenarios

This switch is engineered for environments demanding high reliability, minimal downtime, and resistance to industrial stressors:

  Integrates BACnet/IP controllers, lighting systems, access control, and energy meters in commercial buildings, hospitals, airports, and data centers requiring reliable backbone connectivity.
• Transportation & Logistics
  Used in conveyor systems, automated warehouses (AS/RS), baggage handling, and railway signaling where shock/vibration resistance and extended temperature operation are mandatory.

Technical Specifications & Selection Guide

To ensure optimal performance, review the following parameters when specifying the SCALANCE X108-2 for your project:

Selection Recommendations:
When sizing your network, consider: total number of connected devices, peak data traffic (e.g., HMI visualization + PLC cyclic data), cable run distances (max 100m per segment), and future expansion needs. For networks exceeding 8 nodes, cascade multiple X108-2 units or upgrade to managed SCALANCE X200 series for VLAN segmentation and redundancy protocols (MRP/RSTP). Our engineering team can provide network load calculations and topology diagrams—submit your project parameters for a customized recommendation.

Advanced Capabilities & Customization

• Redundant Power Supply
  Dual 24V DC inputs with automatic failover ensure continuous operation during power source maintenance or UPS switchover events.
• Diagnostic LEDs
  Per-port link/activity indicators plus system power/fault LEDs enable rapid visual troubleshooting without diagnostic tools.
• Conformal Coating (Optional)
  Factory-applied protective coating for deployment in high-humidity, salt-spray, or chemically aggressive environments (offshore, wastewater, mining).
• Extended Warranty Programs
  Available service contracts include advance replacement, on-site commissioning support, and priority technical hotline access.

Delivery, Service & Quality Assurance

Frequently Asked Questions (FAQ)

Q: How do I integrate the SCALANCE X108-2 with existing non-Siemens automation equipment?
A: The switch supports standard IEEE 802.3 Ethernet, making it fully compatible with PLCs, HMIs, and I/O from manufacturers like Rockwell, Schneider Electric, Mitsubishi, and Omron. Simply connect via RJ45 cables; no proprietary protocols required for basic connectivity. For advanced features like PROFINET, ensure your devices support the protocol.

Q: What is the maximum number of devices I can connect to one SCALANCE X108-2?
A: The switch has 8 physical ports, so you can directly connect up to 8 devices. For larger networks, cascade multiple switches using standard Ethernet uplinks. The MAC address table supports 1024 entries, accommodating complex topologies.

Q: What energy savings can I expect compared to commercial switches?
A: While energy savings depend on network load, the X108-2's fanless design and low 4W typical consumption reduce operating costs by approximately 40–50% versus actively cooled commercial switches, especially in 24/7 industrial operations. Additionally, elimination of fan failures cuts maintenance expenses.

Q: What are the environmental requirements for installation?
A: Operating temperature: -40°C to +70°C; humidity: 5–95% RH non-condensing; protection rating: IP30 standard (upgrade to IP65/67 with optional enclosure). Ensure adequate ventilation in enclosed cabinets and avoid direct exposure to water spray or conductive dust without proper enclosure.

Q: Does the switch support remote monitoring or SNMP management?
A: No, the X108-2 is an unmanaged switch without SNMP, web interface, or remote configuration capabilities. For networks requiring centralized monitoring, diagnostics, or VLAN segmentation, consider the managed SCALANCE X200 or X300 series.

Q: Can I use fiber optic connections instead of copper RJ45?
A: The X108-2 model features only copper RJ45 ports. For fiber connectivity (single-mode or multimode), explore the SCALANCE X100 series with SFP slots or the X200 managed switches with combo ports.
