The Allen-Bradley 2711P-RN8 is a DH+ communication module designed specifically for the PanelView Plus 400 and 600 series terminals. It facilitates seamless communication between industrial devices, such as computers, PLCs, and SLCs, using DH+ network technology. The module is compatible with the Allen-Bradley 1770-CD shielded twisted cable, which is ideal for connecting with SLC-5/04, PLC-5, PLC-5C, PLC-5E, and ControlLogix controllers. The cable is a Belden 9463 twin axial type with 20 AWG tinned copper conductors and features a range of specifications aimed at ensuring reliable performance in industrial environments. The module should be operated in ambient temperatures of 32 to 131 degrees Fahrenheit, with storage conditions ranging from -13 to 158 degrees Fahrenheit. It supports a non-condensing relative humidity range of 5 to 95% and can operate effectively at altitudes of up to 2000 meters.
