Allen Bradley 1784-KT PLC Communication Interface Module
The Allen Bradley 1784-KT is an 8-bit communication interface module designed to connect personal computers to industrial control networks. Classified as a PC board add-on card, this legacy hardware card enables host systems to communicate via the Data Highway Plus (DH+) protocol. It provides maintenance personnel and system integrators with a physical gateway for programming, monitoring, and troubleshooting legacy processor families including PLC-2, PLC-3, and PLC-5 controllers.
Network Communication and Architecture
This module implements the Data Highway Plus network standard, utilizing an address-selectable architecture to configure node assignments within an industrial communication loop. Operating as an internal bus interface card, it draws power directly from the host computer backplane or system bus, requiring a current draw of 0.40 amperes at 5 VDC. The hardware relies on jumper or switch settings for physical address selection to prevent node conflicts on active DH+ networks.
System Compatibility and Application
The 1784-KT is specifically engineered to interface desktop or industrial computers with older Allen-Bradley PLC platforms. Because it is natively compatible with PLC-2, PLC-3, and PLC-5 processors, it serves as a crucial legacy support tool for facilities maintaining older automation infrastructures where modern USB or Ethernet adapters are not natively supported by the controller hardware.
