The Allen-Bradley 1770-KF2 Data Highway Communication Interface is a standalone Series B module that provides an RS-232C or RS-422A asynchronous link between external serial devices and an Allen-Bradley Data Highway (DH) or Data Highway Plus (DH+) network. By bridging serial equipment to the DH/DH+ network, the KF2 enables data exchange between intelligent serial devices and DH-compatible controllers and peripherals. This configuration is commonly used to connect serial instruments or terminals to legacy PLC networks, expanding interoperability within the Data Highway ecosystem.
