Electrical Substation-Rated 10/100/1000 Mbps Media Converter

RLMCSFP Series

SUBSTATIONEXCLUSIVE DIN RAIL -40º TO +85º

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 subs tations
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 support s
optical transmission media with selec tion of the appropriate ComNet SFP* module. User-selectable link
fault pass-through provides remote indication of a net work fault, and a summar y fault alarm provides a
local or remote indication via a dr y contac t closure in the event of loss of optical link or operating power.
The 10/100/1000BASE-TX por t 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.

FEATURES

› Full duplex transmission of 10/100/1000 Mbps Ethernet:

(1) 10/10 0/1000 BAS E-TX por t an d
(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 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

› 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

› 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
connec ts 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 media converter

and the link for ease in troubleshooting

1CONVERTERFLEXIBILIT Y

› 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
