LIFETIME WARRANTY WWW.COMNET.NET TECH SUPPORT: 1.888.678.9427
FEATURES
› Supports PoE PDs (Powered Devices) requiring PoE (15 watts),
PoE+ (30 watts), or PoE++ (60 watts) operating power
› Full duplex transmission of 10/100/1000 Mbps Ethernet:
(1) 10/100/1000BASE-TX port and
(1) 100BASE-FX or 1000BASE-FX optical 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 fiber, 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 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
› 48 VDC operating power
› 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
› Features 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 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
› For supporting NERC-CIP-014 compliance, and other critical
infrastructure physical security applications where PoE-powered
IP video cameras, access control equipment, perimeter security
sensing devices, etc., are utilized
› 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
› 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 RLMCSFPPOEHO is a substation-rated and industrially hardened Ethernet media converter that
supports Universal PoE (Power over Ethernet) powered devices requiring up to 60 watts of operating power.
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 power supply features redundant 48 VDC inputs, for the highest possible
reliability. The simple to install, plug-and-play RLMCSFPPOE[HO] is DIN-rail or panel-mountable, and is
ideal for mission-critical PoE applications where very high levels of reliability and network availability
are of the utmost importance.
