Description of 1786-RPFS

The Allen-Bradley 1786-RPFS ControlNet Repeater is a fiber module that belongs to the Allen-Bradley 1786 Repeaters series. This repeater is strong and designed with a white paint job. It has two levels, with each forming rectangular shape. The side of the upper level has the cooling fan of the device with a default space to allow ventilation while the name of the brand is written on the uppermost part of the device. The upper part of the first level has an illustrative use of the repeater. The front part of the lower level has the main control and operational keys. Apart from the main port of connection made of metal, there are six other ports with other parts carefully arranged beside one another.

In addition, the modern 1786-RPFS repeater and short-distance fiber module has a distance rating of 0 to 300m, which is typical of normal repeaters. This makes it perform optimally in the extension of networks and conversion of network media. It has an adapter that serves as a source of power to the module. Also, both the modules and adapters have double status indicators that can easily be interpreted during operations; it states whether the data being processed and recovered are error-free or not. This helps users to make informed decisions. Further, the 1786-RPFS ControlNet Repeater uses the 200/230 micron hard-clad silica (HSC) fiber type. It is most compatible with an RPA/B adapter. Through this adapter, the 1786-RPFS ControlNet Repeater generates an input power of 5V DC. This is expertly supported with a 300 mA backplane current draw. In conclusion, the 1786-RPFS ControlNet Repeater has 650 nm red fiber operating wavelength. It is supported with 4.2 dB attenuation levels.

About 1786-RPFS

The 1786-RPFS repeater module is a short-distance fiber repeater module manufactured by Allen-Bradley. It is used in the industrial sector to extend the length of a network. It is also used to create a star, ring, or point to point topology. It also helps with media conversion from copper to fiber media and vice versa. This short-distance module is powered with a voltage source of 24 Volts DC. It connects 2 ControlNet products with a fiber link. The 1786-RPFS repeater module can work properly at up to a distance of 300 meters between 2 ControlNet modules. This repeater module also has ground isolation between nodes and is less affected by noise than other repeater modules.

The 1786-RPFS repeater modules comprises different components. A backplane connector is present on the left side of the module and there are LED indicators on the top to relay information about Channel 1 and Channel 2. A module locking tab is also included alongside the Channel 1 and Channel 2 fiber ports. There are protective caps on the fiber ports for additional safety. The 1786-RPFS repeater module is powered with 300 milliamps of current and 5 Volts DC maximum voltage. The module consumes a total power of 1.5 Watts. The repeater uses 200/230 type HCS fiber and it supports a communication rate of 5 Mbps. The fiber temperature range should be between -20 and 80 degrees Celsius. The bend radius of the fiber is 1.5 inches during installation and 0.4 inches during operation. The fiber has an operating wavelength of 650 nm and the transmitter output is greater than 5 mW/square millimeter.
