1770-KF2 | Allen-Bradley Data Highway/Data Highway Plus Asynchronous Interface

Description 

The 1770-KF2 is a communication module from Allen-Bradley. This module is specifically a Data Highway or Data Highway Plus Asynchronous interface module supporting RS-232-C or RS-422-A. This module comes with a 15-pin male EIA D-connector for Data Highway; a 15-pin male EIA D-connector for Peer Communication Link; a 9-pin female EIA D-connector for Data Highway Monitor and a 25-pin male EIA D-connector for Asynchronous (RS-232-C/RS-422-A). It supports the standard communication data rate of the compatible communication protocols. It is designed for tabletop mounting within a controlled environment such as an office or control room.

Technical Specifications 

Information About 1770-KF2

The 1770-KF2 is a communication interface module from Allen-Bradley. This module is specifically a Data Highway or Data Highway Plus Asynchronous interface module supporting RS-232-C or RS-422-A electrical standards. It is mainly used to provide point-to-point and multi-drop communication capability that supports the mentioned electrical standards. It is compatible for use with Allen-Bradley Advisor 2+TM Color Graphic System; PLC-3 Programmable Controller and Connected Communication Adapter Module with catalog number 1775-KA; PLC-2 Family Programmable Controller and Connected PLC-2 Family/RS-232-C Interface Module with catalog number 1771-KG; PLC-4 Microtrol Programmable Controller and Connected Communication Interface Module with catalog number 1773-KA; Minicomputers and Microcomputers. The 1770-KF2 comes with a 15-pin male EIA D-connector for Data Highway interfacing; a 15-pin male EIA D-connector for Peer Communication Link; a 9-pin female EIA D-connector intended for Data Highway Monitor and a 25-pin male EIA D-connector for Asynchronous RS-232-C/RS-422-A connection. Supported communication rates are 57,600 bits per second for data highway and peer communication links while the asynchronous link is selectable from 110 to 9600 bits per second. The compatible communication cable is 1770-CD for the data highway. This interface module is designed for tabletop mounting or installation to any flat surface. To ensure continuous operation, it is recommended to be placed inside a controlled environment such as a control room or office area. The module’s input voltage requirement is 115 V/60 Hz or 230 V/50 Hz and has a power rating of 3.5 Watts. It has an operating temperature requirement of 32oF to 113oF (0oC to 45oC) and ambient humidity of 10% to 80% Non-Condensing. The module’s storage temperature is -40oF to 185oF (-40oC to 85oC).

The Allen-Bradley 1770-KF2 communication interface module connects intelligent RS-422-A asynchronous devices or RS-232-C devices to a local area network. When the users change the cables and configuring KF2 switches, the communications will be directed over a Peer Communication Link (PCL) or the Data Highway. The module has been designed to be operated on a tabletop or a horizontal surface and in a control-room environment such as an office. The power is sourced from an AC wall outlet. It offers either half-duplex or full-duplex protocol. The Allen-Bradley 1770-KF2 module has communication rates that include the Data Highway with 57,600 bits per second, the Peer Communication Link with 57,600 bits per second, and the Asynchronous Switch with 110 to 9,600 bits per second. The Allen-Bradley 1770-KF2 communication interface module can be a stand-in for the 1771-KD communication controller module.

The Allen-Bradley 1770-KF2 module has 4 communication ports including the Data Highway port with a 15-pin male Electronic Industries Association D-connector, the Peer Communication port with a 15-pin male Electronic Industries Association D-connector, the Data highway monitor port with a 9-pin female Electronic Industries Association D-connector, and the Asynchronous RS-422-A or RS-232-C ports with a 25-pin male Electronic Industries Association D-connector. The Allen-Bradley 1770-KF2 communication interface module has 3 cabling categories which are the Data Highway (Cat. No. 1770-CD), Asynchronous RS-422-A, and the Asynchronous RS-232-C cabling categories. In addition, it has an ambient operating temperature range from 32 to 113 degrees Fahrenheit (0 to 45 degrees Celsius) and an ambient storage temperature range from -40 to 185 degrees Fahrenheit (-40 to 85 degrees Celsius). It has a non-condensing ambient humidity range from 10 to 80%.
