Allen-Bradley 1784-PKTXD RIO DH485 DH Comm PCI Bus Card

Allen-Bradley 1784-PKTXD is a two-channel PCI Data Highway Plus (DH+) communications card that lets a PC or PC-based controller connect to DH+ networks and Remote I/O (RIO). On Channel 1, it provides a DH+ path with DH-485 support and an integrated RIO Scanner, while Channel 2 offers a DH+ path with a second RIO Scanner. The card's host interface is PCI Bus and it is classified as a Remote I/O peripheral powered by the PCI slot. This PKTx family PCI card bridges a computer to DH+/DH-485 and RIO networks, enabling data exchange for monitoring, data collection, and control tasks across legacy automation networks. Rockwell Automation lists the 1784-PKTXD as discontinued as of March 31, 2022, making it a legacy interface option for connecting PC-based systems to DH+/RIO networks.
