{"product_id":"allen-bradley-1784-kt-plc-communication-interface-module","title":"Allen Bradley 1784-KT PLC Communication Interface Module","description":"\u003cp\u003eThe Allen Bradley \u003cstrong\u003e1784-KT\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003ch3\u003eNetwork Communication and Architecture\u003c\/h3\u003e\n\u003cp\u003eThis 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.\u003c\/p\u003e\n\u003ch3\u003eSystem Compatibility and Application\u003c\/h3\u003e\n\u003cp\u003eThe \u003cstrong\u003e1784-KT\u003c\/strong\u003e 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.\u003c\/p\u003e\n\u003cfigure class=\"table\"\u003e\n\u003ctable\u003e\n\u003cthead\u003e\n\u003ctr\u003e\n\u003cth\u003e\u003cstrong\u003eParameter\u003c\/strong\u003e\u003c\/th\u003e\n\u003cth\u003e\u003cstrong\u003eSpecification\u003c\/strong\u003e\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003e1784-KT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBrand\u003c\/td\u003e\n\u003ctd\u003eAllen Bradley\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct Line\u003c\/td\u003e\n\u003ctd\u003ePLCs \/ Machine Control\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eModule Type\u003c\/td\u003e\n\u003ctd\u003ePC Board PLC \/ Add-On Board\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommunication Protocol\u003c\/td\u003e\n\u003ctd\u003eData Highway Plus (DH+)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCompatible Controllers\u003c\/td\u003e\n\u003ctd\u003ePLC-2, PLC-3, PLC-5\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eBus Interface\u003c\/td\u003e\n\u003ctd\u003e8-Bit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Consumption\u003c\/td\u003e\n\u003ctd\u003e0.40 A at 5 VDC\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eWeight\u003c\/td\u003e\n\u003ctd\u003e0.30 lbs (0.14 kg)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003c\/figure\u003e\n\u003cp\u003eFrequently Asked Questions\u003c\/p\u003e\n\u003cp\u003eQ: Which controller models are supported by the 1784-KT communication interface module?
