Allen-Bradley ControlNet 1786-RPFM Installation Instructions Manual
Allen-Bradley ControlNet 1786-RPFM:
The Allen-Bradley ControlNet 1786-RPFM is a modular repeater medium-distance fiber module designed to provide ground isolation and noise reduction in ControlNet networks. It supports fiber links up to 3000 meters (9843 feet) and features two fiber channels for redundant or expanded network configurations. The module includes activity LED indicators for each channel for easy status monitoring. It is suitable for use in medium-distance fiber optic applications requiring reliable data transmission and noise immunity.

2 ControlNet Modular Repeater Medium-distance Fiber Module
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

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 30 o angle.
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.

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.
