- Buffers multicast and broadcast packet streams with per-port buffering
- Supports simplex, dual, and TMR controller redundant configurations
Application Scenarios:
- Central IONet switching in Mark VIe control cabinets with numerous I/O packs
- Gas and steam turbine control systems requiring redundant fiber uplinks to remote nodes
- Power plant network infrastructure with dual-fiber redundant topologies
- Industrial automation requiring high-density Ethernet switching with dual fiber extension
Performance Parameters:
- Wire-speed forwarding on all 18 ports
- Low switch latency for real-time IONet traffic
- Robust buffering for multicast-heavy control networks
- Industrial-grade reliability with redundant power and wide temperature range
- Fiber ports support distances up to 2 km for multimode fiber
Material and Structural Characteristics:
- Industrial-grade metal housing with convection cooling
- Sixteen RJ45 ports and two LC fiber ports on the front panel
- DIN-rail or panel-mount enclosure with seven panel-mount screw holes
- RJ45 connectors rated for 200 insertion/removal cycles
- Weight: approximately 1.05 kg
Working Principle: The switch forwards Ethernet packets between sixteen copper-connected IONet devices and two fiber-connected uplinks, buffering multicast and broadcast streams. It auto-negotiates speed and duplex on copper ports, supports two 100 Mbps multimode fiber uplinks for redundancy or extended distance, and uses HP-MDIX for copper cable orientation. Redundant 24/28 V DC power inputs ensure continuous operation during power supply failures. Installation Requirements:
- Mount on DIN rail using clips (259B2451BVP1 for horizontal, 259B2451BVP4 for vertical) or panel-mount with seven screws
- Connect 24/28 V DC to redundant power inputs
- Wire copper ports using Cat 5e or better UTP cabling with RJ45 connectors
- Connect fiber ports using multimode fiber with LC connectors
- Ensure adequate ventilation for convection cooling
- Observe maximum 200 insertion/removal cycles for RJ45 connectors
Usage Notes:
- Use only LC-type connectors for the multimode fiber ports
- Select ESWBH1A for one fiber port or ESWBH3A for no fiber ports based on network requirements
- Monitor LED indicators for link status, activity, and power
- Avoid applying torsional stress or cable-weight tension on fiber or copper connectors
- Confirm power supply voltage and polarity before energizing
- Replace with identical ESWB series models to maintain network configuration
