Comnet Electrical Substation-Rated 10/100/1000 Mbps 3-Port Self-managed Ethernet Switch - 3 Ports - Manageable - 2 Layer Supported - Modular - Twisted Pair, Optical Fiber - DIN Rail Mountable, Panel-mountable, Wall Mountable - Lifetime Limited Warranty RL

The ComNet RLGE2+1SMS is a substation-rated and industrially hardened three-port self-managed switch with uplink management functionality. Fully compliant with the requirements of IEC 61850-3, IEEE 1613 Class 2, EN50155, and NEMA TS-1/TS-2, it is designed 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, trackside and roadside electronic equipment, and other difficult out-of-plant applications. The DIP-switch-selectable 100BASE-FX or 1000BASE-FX port supports conventional CAT-5e/CAT-6 copper or optical transmission media by selection of the appropriate ComNet SFP* module. User-selectable link fault pass-through provides remote indication of a network fault, and two summary fault alarms provide a local or remote indication via dry contact closures in the event of loss of optical link or operating power. The 10/100/1000BASE-TX ports support both auto-negotiation and automatic MDI/MDI-X crossover for full and half-duplex operation; manual MDI/MDI-X switching is not required. The RLGE2+1SMS comes pre-programmed, preventing network video flooding with DIP-switch selection of the SFP port as uplink or as an unmanaged switch. The internal/self-contained 12 to 24 VDC, 48 VDC, or HV AC/DC power supply features redundant power inputs when used with 12 to 24 VDC or 48 VDC power sources, for the highest possible reliability. The simple to install, plug-and-play RLGE2+1SMS is DIN-rail or panel-mountable, and is ideal for mission-critical applications where very high levels of reliability and network availability are of the utmost importance.FEATURES: Full duplex transmission of 10/100/1000 Mbps Ethernet: (2) 10/100/1000BASE-TX ports and (1) 100BASE-FX or 1000BASE-FX SFP port Designed to the requirements of IEC 61850-3 and IEEE 1613 Class 2 for electrical utility substations, EN50155 for railway applications, and NEMA TS-1/TS-2 for traffic signal control equipment, and IEC/EN60950-1 Extended ambient operating temperature range of -40º to +85º C, for use in virtually any environment. Optional conformal coating available for humidity with condensation or airborne particulate matter environments Uses customer-installed ComNet SFPs for compatibility with a wide range of optical fibers, optical connector types, and optical transmission distances of up to 120 km Link fault pass-through provides a remote indication of a network fault 10/100/1000BASE-TX ports support both auto-negotiation and automatic MDI/MDI-X crossover for full and half-duplex operation; manual MDI/MDI-X switching is not required 12 to 24 VDC, 48 VDC or HV AC/DC (88 to 300 VDC/85-264 VAC) operating power options Internal/self-contained high-reliability power supply eliminates the need for an external power supply, and a screw terminal block connects directly to the power source for permanent, reliable, and maintenance-free operation 12 to 24VDC and 48 VDC input power supply versions feature redundant power inputs, for extremely high levels of reliability and availability No fans or forced-air cooling required; cooling via natural convection eliminates unreliable and troublesome fans/moving parts for improved reliability Indicating LEDs confirm operating status of the switch and the link for ease in troubleshooting Summary fault alarms provide a local or remote indication via dry contact closures in the event of loss of optical link or operating power
