Allen-Bradley 1770-KF2 DH+ Interface Module – PLC-2 Family
When a Data Highway Plus (DH+) communication link goes down on the plant floor, the consequences are immediate and costly: PLCs lose peer-to-peer coordination, SCADA systems go blind, and production lines halt without warning. The Allen-Bradley 1770-KF2 Interface Module is the critical bridge that keeps your PLC-2 family controllers connected to the DH+ network — a role no generic substitute can reliably fill.
Within the PLC-2 product family, the 1770-KF2 occupies a specialized position as the dedicated DH+ network interface, enabling seamless communication between legacy PLC-2 controllers and modern Data Highway Plus architectures. Globally, this module remains an essential spare and replacement part for thousands of manufacturing facilities running Allen-Bradley automation infrastructure built in the 1980s and 1990s — systems that continue to operate reliably decades after installation.
