ComNet product series RLGE20FX4TX16MS is a substation-rated and industrially-hardened DIN-rail mount all-gigabit managed layer 2 switch. Fully compliant with the requirements of IEC 61850-3, IEEE 1613 Class 2, EN50155, and NEMA TS-1/TS-2, the RLGE20FX4TX16MS is intended for deployment in environments where high levels of electromagnetic noise and interference (EMI) and severe voltage transients and surges are routinely encountered, such as electrical utility substations and switchyards, heavy manufacturing facilities, track-side electronic equipment, and other difficult out-of-plant installations. The RLGE20FX4TX16MS provides 16 10/100/1000BASE-TX communications ports, with 4 10/100/1000BASE-TX or 100/1000BASE-FX SFP uplink ports. The use of SFPs for the four (4) gigabit uplink ports provides a truly future-proof platform where the uplink optics may be changed in the field at any time, to support changes in the user’s networking or cable plant requirements as they arise. The internal/self-contained 12 to 60 VDC or 85 to 264 VAC/88 to 373 VDC power supply features redundant power inputs, for the highest possible reliability in those installations where network availability is of the utmost importance. The RLGE20FX4TX16MS supports multiple Ethernet redundancy protocols, including ComNet C-Ring (recovery time < 30ms, with >250 switches integrated within the ring), and MSTP with RSTP/STP compatibility. With its extremely fast recovery time, the most mission-critical applications are fully protected from network interruptions or temporary malfunctions due to possible short or long-term faults or outages within the network.

Features for RLGE20FX4TX16MS Series

  • IPV6 internet protocol (latest version)
  • Device Binding security function
  • IGMP v2/v3 (IGMP snooping support) for filtering multicast traffic
  • Fully compliant with the requirements of IEC 61850-3 and IEEE 1613 Class 2, for use in electrical utility substations; NEMA TS-1/TS-2 for Traffic Signal Control Equipment; and EN50155 for railway applications
  • 16 × 10/100/1000BASE-TX Mbps Ethernet RJ-45 communications ports
  • 4 × 100/1000BASE-X gigabit SFP uplink combo ports provide flexibility and simplify network planning, & allows for future user field upgrades and system/cable plant changes without having to replace the switch
  • Redundant power supply inputs significantly reduce the possibility of a single-point-of-failure, for the highest system and network reliability. Multiple AC and DC operating voltages available
  • Supports IEEE 1588v2 Precision Timing Protocol, Transparent Clock Synchronization (TC), for protective relaying and control applications
