Phoenix Contact FL MC 10BASE-T/FO G850 User manual

1. Description
The FL MC 10BASE-T/FO G850 medium converter
provides a high level of noise immunity and a long
transmission range in industrial applications by
converting the 10 BASE-T Ethernet interface to optical
fibers.
The device can be operated individually as well as in
modular hub stations.The supply voltage is 24V DC.
In FL hub stations, the supply voltage is supplied to all
the connected devices via a backplane integrated in
the base of the device.In individual operation, the
supply is provided using plug-in screw-clamp
terminals.
The converter has a link monitoring function, which
separately indicates/monitors the operability of the
cable connection and the connected devices for theTP
and optical fiber channels.It also automatically detects
pairs of incorrectly connected receiving cables at the
TP connection and corrects them using the auto
polarity correction function.
If long distances are to be covered or if an existing
glass fiber installation is used, the FL MC 10BASE-T/
FO G850 converter covers distances up to 2800 m
(9186.35 ft.) using multimode glass fiber.The
connection corresponds to the ST® (B-FOC) standard.
The medium converter conforms to the
specifications of standards IEEE 802.3 and ISO/IEC
68802.3.

Mounting/removing the
FL hub station
6. Push the second module (from the left) along the
DIN rail to the left until the pin strip/socket strip of
both modules are interlatched and the sides of both
modules lie flush with one another.
7. Now push the other modules together from right to
left as described above.
(Figure 08).
Removal:
1. To remove a FL hub station, the FL module on the
right-hand side must be pushed to the right until the
entire pin strip/socket strip is released (Figure 08).
2. Pull the locking latch down using a screwdriver,
needle-nose pliers or similar.
3. Pull the bottom edge of the module away from the
mounting surface.
4. Pull the module diagonally upwards away from the
DIN rail.
Install the FL MC 10BASE-T/FO G850 on a DIN rail
in accordance with DIN EN 50 022 (Phoenix Contact:
item NS 35).To avoid contact resistance only use
clean, corrosion-free DIN rails.End clamps should be
mounted on both sides of the module to stop the
terminals from slipping on the DIN rail.
4.1. Mounting/Removing
Mounting:
1. Fasten an end clamp next to the left-hand module to
stop the modules from slipping.
2. Place the module onto the DIN rail from above.The
upper holding keyway must be hooked onto the top
edge of the DIN rail (Figure 07).
3. Push the module from the front towards the
mounting surface.
4. Once the module has been snapped on properly,
check that it is fixed securely on the DIN rail.
5. Snap the other modules to be contacted onto the
DIN rail side by side.
Only mount and remove modules when
the power supply is disconnected.
When connecting the supply voltage for
operation in a FL hub station, please
refer to the notes.
Attention
Disregarding this warning may result in serious
damage to persons or property.Only qualified
personnel may start up and operate these devices.
According to the safety instructions in this text,
qualified personnel are persons who are authorized
to start up, to ground and to mark devices, systems,
and equipment according to the standards of safety
technology.In addition, these persons must be
familiarwithallwarninginstructionsandmaintenance
measures in this text.
The FL MC 10BASE-T/FO G850 module is designed
exclusively for SELV operation in accordance with
IEC 60950/EN 60950/VDE 0805.
Connect the DIN rail to the protective
earth ground using a grounding terminal.
The modules are grounded when they
are snapped onto the DIN rail.This
ensures that the shield is effective.
Connect the protective earth ground with
low impedance.
Only mount and remove modules when
the power supply is disconnected.
Note:The device can be operated individually as well
as in modular FL hub stations.In a FL hub station, the
order of the various module types can be freely
selected.

6.3. Diagnostic Indicators
Link ControlTP Path (RJ45):
The line monitoring checks the connected cable
segment for a short circuit or interrupt.To do this, the
partner must send link or data signals.The LED
(green) lights up if no error has occurred.An interface
that is not being used or a terminal device that is
switched off is indicated as an error and the LED goes
out.
Data ControlTP Path (RJ45):
The data LED (yellow) flashes depending on the
amount of data that is received by the 10Base-T
interface.
The module is operated using a +24 V DC SELV.
5.1. Operation as an Individual Device:
Provide the supply voltage for the module via
terminals US1 and GND.
As an option, an additional power supply unit can be
connected to terminals US2 and GND to provide a
redundant voltage supply.
Both US1/US2 voltages are forwarded on the
backplane (Figure 03).
5.2. Operation in a FL Hub Station:
6.Twisted-Pair Interface (TP Port)
6.1. 10Base-T Interface
The FL MC 10BASE-T/FO G850 has an Ethernet
interface on the front in RJ45 format, to which only
twisted-pair cables with an impedance of 100 Ω can be
connected.The data transmission rate is 10 Mbps.The
interface can detect a pair of incorrectly connected
receivingcables(RD+/RD-) and correct them usingthe
auto polarity correction function.
.
6.2. Connection
Push the Ethernet cable with the
crimped RJ45 connector into interface 1 until it
engages with a click.Observe the encoding of the
connector.
The sum of the nominal currents in a FL
station must not exceed 2 A. Please refer
to the nominal currents specified in the
data sheets for the selected FL modules.
The supply voltage US1, and if applicable
US2, may only be supplied to one of the
modules and never to several modules.
If a hub or hub agent is present in the
station, the supply must be provided to
one of these modules.
Only use shielded twisted-pair cables
and corresponding shielded RJ45
connectors.

General Notes
Follow the cable manufacturer's technical data when
handlingthevariousopticalfiber cables.Inorderfor the
communication path to be protected against
interference, the permissible values for the bending
radii, strain, and pressure strengths must not be
exceeded.

Protective caps should only be removed
just before the connectors are
connected.They protect the send and
receive elements.The same applies to
the protective caps for the connectors.
During operation, do not look directly
into send diodes, or use visual aids to
look into the glass fibers.The infrared
light is not visible.
Be aware of the optical fiber cable signal
direction when coupling two medium
converters:
Module 1 fiber connection "TD" (sender)
to module 2 fiber connection "RD"
(receiver).
