About the Repeater Adapter Module
The 1786-RPA/B ControlNet repeater adapter module, which has a 24V DC,
removable power supply, can be used with 1786 repeater modules to build a
ControlNet network repeater. A repeater is used to extend the length of a
network, create a star, ring, or point-to-point topology, or perform network
media conversion from copper to fiber, and vice versa. A maximum of 20
repeater adapter can be placed in a series.

Page 8: Mount The Repeater Adapter Module
8 ControlNet Modular Repeater Adapter Mount the Repeater Adapter Module This section explains how to mount the 1786-RPA/B repeater adapter module. Horizontal mounting is preferred. Vertical mounting is allowed. We recommend that the 1786-RPA/B module be mounted at the top if vertical mounting is chosen. ATTENTION: This product is grounded through the DIN rail to chassis ground. - Page 9 ControlNet Modular Repeater Adapter 9 Do these steps to mount the 1786-RPA/B module. 1. Position the repeater adapter module on the 35 x 7.5 mm (1.4 x 0.3 in.) DIN rail (Allen-Bradley part number 199-DR1) at a 30 angle. 31454A-M 2.
- Page 10 10 ControlNet Modular Repeater Adapter If the repeater adapter module does not snap into position, use a screwdriver or similar device to move the locking tab down while pressing the repeater adapter flush onto the DIN rail. 31454C-M 4. Release the locking tab to lock the adapter in place. If necessary, push up on the locking tab to lock.
- Page 11 ControlNet Modular Repeater Adapter 11 WARNING: Removal and insertion under power (RIUP) is not supported. This module must be powered down while connecting and disconnecting it from any interconnected modules. If you insert or remove the module while backplane power is on, an electrical arc can occur.
