About The Fiber Module

Use this module when a medium-distance (distances of 3000m/9843ft)

fiber link is required between two ControlNet products. This fiber link

provides ground isolation between nodes and is less susceptible to noisy

environments than traditional cooper media.

Note: The distance that can be supported is dependent on the quality of

the fiber, number of splices, and connectors. The total loss of the

fiber link must be less than 13.3 dB. Typical systems of greater

than 3000m are possible.

The module provides:

•two fiber channels

•activity LED indicators for each fiber channel

The figure below identifies the components of the module:

European Union Directive Compliance

If this product has the

ÎÎ

mark, it is approved for installation within

the European Union and EEA regions. It has been designed and tested to

meet the following directives.

EMC Directive

The module is tested to meet Council Directive 89/336 Electromagnetic

Compatibility (EMC) using a technical construction file and the

following standards, in whole or in part:

•EN 50081-2 EMC – Generic Emission Standard,

Part 2 – Industrial Environment

•EN 50082-2 EMC – Generic Immunity Standard,

Part 2 – Industrial Environment

The module described in this manual is intended for use in an

industrial environment.

Low Voltage Directive

The module is also designed to meet Council Directive 73/23 Low

Voltage, by applying the safety requirements of EN 61131–2

Programmable Controllers, Part 2 – Equipment Requirements and Tests.

For specific information that the above norm requires, see the

appropriate sections in this manual, as well as the following

Allen-Bradley publications:

•Industrial Automation Wiring and Grounding Guidelines,

publication 1770-4.1

•Guidelines for Handling Lithium Batteries, publication AG-5.4

•Automation Systems Catalog, publication B111

Mounting The Fiber Module

To mount the module on the DIN rail:

1. Position the module on a 35 x 7.5mm DIN rail (Allen-Bradley part

number 199-DR1; 46277-3; EN 50022) at a 30oangle.

30074–M

2. Hook the lip on the rear of the module onto the top of the DIN rail,

and rotate the module onto the rail.

3. Press the module down onto the DIN rail until flush.

The locking tab should snap into position and lock the module to the

DIN rail.

4. If the module does not snap into position, use a screwdriver or similar

device to move the locking tab down while pressing the module flush

onto the DIN rail. Release the locking tab to lock the module in place.

If necessary, push up on the locking tab to lock.

5. Remove the protective backplane cap as shown in “Removing the

Protective Caps” on page 7.

6. Once attached to the DIN rail, slide modules to the left to mate with

the repeater adapter or another repeater module.

30043–M

!ATTENTION: Make certain that the adapter and repeater

modules are secured together with DIN rail anchors.

Failure to do so may result in the loss of communications

and/or cause damage to the modules.

The total number of modules that can be attached to the repeater adapter

can not exceed four or the total power consumption of the modules can

not exceed 1.6A @ 5VDC, whichever comes first.

Important: If you exceed the module or power limit, you may cause

damage to the repeater adapter and modules.

Important: If this is the right–most module, a DIN rail latch must be

used on the right–side of the fiber module.

7. Connect the module wiring as shown in “Wiring The Fiber Module”

on page 8.

If: Then:

a channel is not going to be used keep protective caps on channels to protect

unit from dust.

another module will be connected to the right

backplane connector remove the protective backplane cap and save

cap for future use.

a module will not be connected to the right

backplane connector leave the backplane cap attached.

Wiring The Fiber Module

If only one channel is wired, you can use Channel 1 or Channel 2.

To wire the module for Channel 1:

1. Connect to Receive ST.

a. Align the knob of the ST cable connector with the groove of the

ST module connector, and insert the connector into A.

Important: Be sure the fiber connected to A(receive) on one

1786–RPFM is connected to B(transmit) on the other

1786–RPFM. You can use Channel 1 or Channel 2 on

either module.

Important: Never connect the fiber cable between Channel 1 or

Channel 2 on the same repeater module, even between

channels from different modules on the same repeater.

!Warning: Do not look directly into the fiber ports.

Light levels may cause damage to eyesight.
