LIFETIME WARRANTY WWW.COMNET.NET TECH SUPPORT: 1.888.678.9427
FEATURES
› Full duplex transmission of 10/100 Mbps Ethernet:
(1) 10/100BASE-TX port and
(1) 100BASE-FX 2 Fiber optical port
› Designed to the requirements of IEC 61850-3 and IEEE 1613 Class
2 for electrical utility substations, EN50155 and EN50121-4 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
› Link fault pass-through provides a remote indication of a network fault
› 10/100BASE-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
› 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 24 VDC 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
› Indicator LEDs confirm operating status of the media converter
and the link for ease in troubleshooting
› 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
› Rugged 19-gauge galvanized & powder-coated steel enclosure
may be DIN-rail or panel-mounted
› Made in the USA
› Lifetime Warranty
APPLICATIONS
› Electrical substation automation & SCADA networks, protective
relaying systems, and distribution automation
› Power transmission & distribution systems, remote wind farm,
hydroelectric, and solar/photovoltaic power generation facilities,
and other electrical utility-specific applications
› Perimeter security, surveillance monitoring, and controlled access
to electrical substations and power generating facilities, and other
high-value, mission-critical sites
› Industrial/Factory Automation & Process Control SCADA
Networks
› Chemical and petrochemical refining and processing facilities, oil
and gas pipelines/transmission systems, and mining installations
› Food processing operations
› Wastewater treatment plants
› ITS/Transportation Traffic Signalization & Surveillance/Incident
Detection Networks
› Railway/trackside control and monitoring systems
› Integrated IP-Video, VOIP, and Data Transmission Networks
› Cellular telephony and wireless backhaul networks
The ComNet RLMC100X 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 100BASE-FX port supports conventional
optical transmission media by fixed 2-fiber ST or SC optical connectors. 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
10/100BASE-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 RLMC100X(M,S)2 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.
