Allen-Bradley 1784-KTX ISA Communication Module – ControlLogix DH+/RIO Series
When a critical communication link between your PLC and field devices goes down, production halts — conveyor lines stop, batch processes abort mid-cycle, and maintenance teams scramble under pressure. In DH+ and Remote I/O (RIO) network environments, the ISA-bus communication card is the invisible backbone that keeps data flowing between your PC workstation and the Allen-Bradley control system. Without a reliable, compatible module in that ISA slot, your entire SCADA interface, programming terminal, and diagnostic visibility disappear instantly.
The Allen-Bradley 1784-KTX is a factory-original ISA-form-factor communication module engineered specifically for Rockwell Automation’s Data Highway Plus (DH+) and Remote I/O (RIO) network architectures. Within the 1784 series — Rockwell’s dedicated PC-based communication card family — the KTX variant occupies the dual-port, ISA-bus position, making it the go-to solution for legacy and hybrid automation environments worldwide where ISA-slot workstations remain in active service. Its continued demand in global industrial markets reflects the enormous installed base of Allen-Bradley PLC-5, SLC 500, and MicroLogix systems still running in manufacturing, oil & gas, water treatment, and automotive plants across North America, Europe, and Asia.

Our Quality Assurance Process
Every Allen-Bradley 1784-KTX unit shipped from Konmask.com passes through a structured inspection and verification process:
- Visual Inspection: PCB, connectors, and edge contacts checked for physical damage, corrosion, or component anomalies.
- Functional Testing: Module is bench-tested for DH+ and RIO communication handshake with RSLinx Classic to confirm driver recognition and network enumeration.
- Firmware / Revision Verification: Hardware revision and firmware version documented and disclosed prior to shipment.
- ESD-Safe Packaging: All units are packed in anti-static bags with foam cushioning to prevent transit damage.
- Traceability: Each unit is logged with inspection date, test result, and technician ID for full accountability.

Frequently Asked Questions
Q: Is the 1784-KTX compatible with Windows 10 or Windows 11?
A: The 1784-KTX is an ISA-bus card and requires a physical ISA slot, which is not present in modern PCs. It is designed for use with older industrial workstations running Windows XP or Windows 7 with RSLinx Classic. For modern PC connectivity to DH+ networks, consider the 1784-U2DHP USB adapter instead.
Q: What is the difference between the 1784-KTX and 1784-KTX/B?
A: The 1784-KTX/B is a later hardware revision of the same card with minor component updates. Both support the same DH+ and RIO functionality and use the same RSLinx driver. Functionally, they are interchangeable in most applications.
Q: Can the 1784-KTX communicate with ControlLogix (1756) systems?
A: The 1784-KTX connects to DH+ and RIO networks. ControlLogix systems use EtherNet/IP or ControlNet natively. However, if your ControlLogix system includes a 1756-DHRIO bridge module, the 1784-KTX can communicate with it via the DH+ network segment.
Q: Do you provide a warranty on the 1784-KTX?
A: Yes. All tested and refurbished units carry a 90-day functional warranty. New/sealed units follow the manufacturer’s original warranty terms. Please contact us for details specific to your order.
Q: How long does international shipping take?
A: Standard express shipping (DHL/FedEx) typically takes 3–7 business days to most destinations. We ship from China and provide full tracking and export documentation.
