The ComNet RLMC Series is a substation-rated and industrially hardened Ethernet media converter. Designed to the requirements of IEC 61850-3, IEEE 1613 Class 2, EN50155, and NEMA TS-1/TS-2, it 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, trackside and roadside electronic equipment, and other difficult out-of-plant applications. The DIP-switch-selectable 100BASE-FX or 1000BASE-FX port supports optical transmission media with selection of the appropriate ComNet SFP module. User-selectable link fault pass-through provides remote indication of a network fault, and a summary fault alarm provides a local or remote indication via a dry contact closure in the event of loss of optical link or operating power. The 10/100/1000BASE-TX port supports both auto-negotiation and automatic MDI/MDI-X crossover for full and half-duplex operation; manual MDI/MDI-X switching is not required.
The internal/self-contained 12 to 24 VDC or 48 VDC power supply features redundant power inputs for the highest possible reliability. A high voltage AC/DC option is also available. The simple to install, plug-and-play RLMCSFP 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.
