Allen-Bradley 1784-KT Industrial Communication Module

Allen-Bradley 1784-KT Industrial Communication Module is an ISA bus DH+ interface card that bridges a PC to Allen-Bradley Data Highway Plus networks, enabling communication with PLC-5 and compatible SLC controllers on established DH+ installations. The module serves as the hardware link between the host computer and the DH+ network, allowing PC-based software to read and write data on the PLCs and integrate with HMI or SCADA systems. Variants in the 1784-KT family (such as 1784-KT/B) reflect different packaging options within this legacy interface line. Designed for use with legacy AB control architectures, the 1784-KT supports data exchange over DH+ networks through the dedicated interface hardware.
