About the Module

Use the 1786-RPFM module when you need a medium-distance fiber link
between two ControlNet products. Maximum distance is 3000 m (9843 ft). The
fiber link provides ground isolation between nodes and is less susceptible to
noisy environments than copper media.

The supported distance depends on the quality of the fiber,
number of splices, and connectors. The total light loss through
the fiber link must be less than 13.3 dB.

Environment and Enclosure

ATTENTION: This equipment is intended for use in a Pollution

Degree 2 industrial environment, in overvoltage Category II
applications (as defined in IEC 60664-1), at altitudes up to 2000 m
(6562 ft) without derating.

This equipment is considered Group 1, Class A industrial equipment
according to IEC/CISPR 11. Without appropriate precautions, there
may be difficulties with electromagnetic compatibility in residential
and other environments due to conducted and radiated disturbances.

This equipment is supplied as open-type equipment. It must be
mounted within an enclosure that is suitably designed for those
specific environmental conditions that will be present and
appropriately designed to prevent personal injury resulting from
accessibility to live parts. The enclosure must have suitable
flame-retardant properties to prevent or minimize the spread of flame,
complying with a flame spread rating of 5VA, V2, V1, V0 (or
equivalent) if non-metallic. The interior of the enclosure must be
accessible only by the use of a tool. Subsequent sections of this
publication may contain additional information regarding specific
enclosure type ratings that are required to comply with certain
product safety certifications.

In addition to this publication, see:

• Industrial Automation Wiring and Grounding Guidelines, Rockwell

Automation publication 1770-4.1
requirements.

• NEMA Standard 250 and IEC 60529, as applicable, for explanations

of the degrees of protection provided by different types of enclosure.

Module Components

The illustration shows the components that comprise the 1786-RPFM module.

Mount the Module

Mount the module on a 35 x 7.5 mm (1.38 x 0.30 in.) DIN rail, Allen-Bradley
part number 199-DR1, 46277, EN 50022.

ATTENTION: This product is grounded through the DIN rail to
chassis ground. Use zinc-plated yellow-chromate steel DIN rail to
assure proper grounding. The use of other DIN-rail materials (for
example, aluminum or plastic) that can corrode or oxidize, or are
poor conductors, can result in improper or intermittent grounding.
Secure DIN rail to mounting surface approximately every
200 mm (7.87 in.) and use end-anchors appropriately.

When using the 1786-RPFM module, we recommend horizontal
mounting if cabinet temperatures are expected to approach
60 °C (140 °F). If your expected temperatures are much lower
than 60 °C (140 °F), vertical mounting is acceptable. If using

Rockwell Automation Publication 1786-IN011C-EN-P - November 2010

vertical mounting, we recommend that the 1786-RPA repeater
adapter module be mounted at the top.

Consult with your local distributor for attenuation specifications
before you purchase your fiber media components.

IMPORTANT

IMPORTANT

You can attach a maximum of four modules to the repeater adapter, or, the
number of modules whose total power consumption does not exceed

1.6 A @ 5V DC, whichever occurs first.

If you exceed the module or power limit, you may damage the
repeater adapter and modules.

Select Fiber Cable

The type of fiber cable you choose depends on the network environment. The
quality of fiber cable determines the distance you can achieve. The maximum
length of a fiber cable section for the module depends on the quality of fiber,
number of splices, and the number of connectors. The total attenuation for a
cable must be less than 13.3 dB. Typically, cable attenuation for a wavelength of
1300 nm is less than 1.5 dB/km.

Refer to the specification table on page
Media Planning and Installation Guide, publication CNET-IN001
details.

Also, consult with your local distributor for attenuation specifications before
you purchase your fiber media components.

Avoid splicing your cable. Connectors can cause considerable
attenuation and limit the maximum length of your system. Make
certain to check the attenuation of different cable sections after
you install the cable.

, for more

Terminate Your Cable

You must terminate a medium distance cable in the field. To terminate, we
recommend that you cover unused ports with a suitable protector cap to prevent
dust and other contaminants from damaging the fiber transceiver ports.

For unused ports, we recommend that you place a simplex jumper between the
transmit port and receive port of an unused channel.

Rockwell Automation Publication 1786-IN011C-EN-P - November 2010

ControlNet Modular Repeater Medium-distance Fiber Module 11

IMPORTANT

Connect the Fiber Module

If you are wiring only one channel, you can use either channel 1 or channel 2.

Do these steps to connect to channel 1, receive (RX).

1. Align the knob of the cable connector with the groove of the module
connector.

2. Insert the connector into channel 1 RX.

3. Twist the receive connector until the bayonet lug locks into place.

4. Repeat these procedures to connect to channel 1, transmit (TX).

Make certain the fiber cable you connect to channel 1 ( receive)
on one module is set to channel 1 (transmit) on the other module.
You can use channel 1 or channel 2 on either module.

ATTENTION: Under certain conditions, viewing the optical port
may expose the eye to hazard. When viewed under some
conditions, the optical port may expose the eye beyond the
maximum permissible exposure recommendations.
