4 Ethernet Ports with Single/Dual Fiber Optics

  • Three configurations to choose from:
    2x 10/100TX ports + 1x 100FX port (SC/ST)
    2x 10/100TX ports + 2x 100FX port (MTRJ/LC)
    4x 10/100TX ports

  • Multimode and single-mode optical transceivers

  • Industry standard fiber-optic connectors: LC, SC, ST, MTRJ

  • Long-haul optics allow distances from 20 km to 90 km


Universal Power Supply Options

  • Input voltages of 24 VDC, 48 VDC, and high-voltage (88–300 VDC or 85–264 VAC) for worldwide operability

  • Integrated power supply eliminates need for an awkward external power transformer

  • Screw-down terminal blocks ensure reliable, maintenance-free connections

  • CSA/UL 60950 safety approved to +85°C



Designed for Harsh Environments

  • Exceeds IEC 61850-3 and IEEE 1613 (electric power substations)

  • Exceeds NEMA TS-2 (traffic control equipment)

  • Operates over a temperature range of –40°C to +85°C without the use of fans for improved reliability

  • 21 AWG galvanized steel enclosure and DIN or panel mounting options provide secure mechanical reliability


High-Performance Ethernet Switching

  • Full compliance with IEEE 802.3 and IEEE 802.3u Ethernet standards for universal interoperability

  • Non-blocking, store and forward switching with only 10 µs latency for high network throughput

  • Full duplex operation results in no collisions

  • Deterministic network response and flow control via 802.3x pause frames results in no collisions or dropped packets


Simple Plug and Play Operation

  • Automatic learning of up to 2,048 MAC addresses

  • Auto-negotiation on 10/100TX ports simplifies setup

  • Auto-MDI/MDIX on all 10/100TX ports eliminates need for crossover cables

  • LED indicators for link, activity, and speeds aid in field
