Product Summary

The Allen-Bradley 1784-PKTX is a reliable network interface card. It mounts directly to a PCI port. This card connects your computer to Data Highway Plus or Remote I/O networks. It effectively supports process visualization with PLC-5 and SLC controllers.

[Theme A: Product Procurement & Buyer Guide]

This card solves key communication challenges. It gives you one channel for DH+ and Remote I/O. A separate channel handles DH-485 networks. You can connect to PLC-5, SLC 5/04, and other processors. This flexibility reduces the need for multiple interface cards. The module operates in a 0 to 60 degrees Celsius range. This temperature tolerance fits most factory floor environments. It withstands 30G operational shock and 2G vibration. These features ensure long-term durability in harsh settings. Procurement managers gain a single solution for multiple legacy networks. The 1784-PKTX delivers strong value for upgrading older systems. It requires no external power supply for operation. This reduces installation complexity and total system cost. You can install up to four modules per system. This scalability helps you expand your network connections gradually.

[Theme D: Expert Technical Evaluation & Performance Review]

The card supports PCI bus version 2.3 for modern compatibility. It communicates with DH+ at 57.6K bits per second over 10,000 feet. You can increase speed to 230.4K bits per second over 2,500 feet. For DH-485, it reaches 4,000 feet at 19,200 bits per second. These rates ensure reliable data transfer across large facilities. The module has conformal coating for environmental protection. Typical AC signal delay measures 29 milliseconds plus or minus 8. This precise timing supports accurate process control applications. The card uses only 0.3 pounds of weight. Its compact size fits easily into a standard PCI slot. One diagnostic LED per channel gives immediate status feedback. This feature helps technicians quickly identify network faults. The card supports the Remote I/O scanner function. It works with the RSLinx PKTx driver for simple configuration. The 1784-PKTX provides a robust, stable bridge between your PC and control networks.
