Description

The Allen-Bradley 1784-KTX is a legacy, high-performance Communication Interface Card designed to establish a direct connection between an industrial or personal computer and Allen-Bradley automation networks. It is engineered to occupy a standard 16-bit ISA (Industry Standard Architecture) or EISA expansion slot on a computer motherboard. The module acts as an intelligent network node that offloads communication processing tasks from the host computer's primary CPU, ensuring high-speed data throughput without lagging. Featuring a 9-pin D-shell subminiature physical port, the 1784-KTX card allows the host PC to communicate directly with Data Highway Plus (DH+) networks, DH-485 networks, or to act as a remote I/O scanner interface. This makes it a foundational tool for industrial software programming, configuration, and real-time Human-Machine Interface (HMI) data acquisition.
