The catalog number 1775-WB belongs to the peripheral communication mod terminal wiring arm, manufactured by Allen Bradley; this part is compatible with the peripheral communication modules of the 1755 series. The Allen-Bradley 1775-WB peripheral communication mod terminal wiring arm is located at the bottom of the front edge of the communication terminal; it consists of an extension that provides connections for two remote channels onto the communication terminal. The Allen-Bradley 1775-WB peripheral communication mod terminal wiring arm provides two remote wiring channels, which can be connected to either a compatible system like the one from the 1770 series or to a maximum of sixteen 1775-RM adapters. Each one of these wiring channels can provide a means for communication with external devices, such as computers, data terminals, printers, modems, recorders, robots, barcode readers, and others.

The importance of this Allen-Bradley 1775-WB peripheral communication mod terminal wiring arm lies in the extra connections that it can offer to a communication device, which can improve the whole process since it offers the opportunity to have external devices involved, which at the same time can give operators a totally different view of the process. Similarly to many Allen-Bradley parts, this part has environmental conditions that must be maintained in order to preserve its correct functioning and performance. These conditions are an operational temperature range from 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit) and a relative humidity range from 5 to 95%. This unit has an approximate shipping weight of 0.37 pounds which equals to 136 grams.
