Information About 1784-PKTX 

The 1784-PKTX is a PCI 2.3–compliant communication card built for integration with Allen-Bradley’s PLC-5, SLC, and related legacy industrial automation platforms. It features one DH+/RIO channel and one DH-485 channel, enabling the PC to participate on multiple network types within the same installation. The module is designed for use in systems requiring long-distance communication, offering extended cable lengths based on selectable data rates. It is commonly used in diagnostic, supervisory, and data-collection applications where PCs must interface directly with established DH+, RIO, or DH-485 infrastructures.

Key Features:

  • Dual-Protocol Support: Provides DH+/RIO communication on Channel 1A and DH-485 communication on Channel 1C for flexible integration.
  • PCI 2.3 Interface: Operates through a standard PCI bus, allowing installation in compatible industrial or commercial PCs.
  • Extended Cable Distances: Supports up to 10,000 ft on DH+/RIO and up to 4,000 ft on DH-485 depending on baud rate.
  • Diagnostic Indicators: Includes one status LED per channel for real-time network activity and fault monitoring.
  • Multi-Module Support: Allows up to four cards per system for expanded connectivity.
  • Controller Compatibility: Interfaces with PLC-5, SLC 5/04, and other supported controllers via RSLinx PKTx drivers.
  • No External Power Required: Draws power directly from the PCI bus for simplified installation.
  • Environmental Durability: Rated for industrial shock, vibration, and operating temperature conditions.

The 1784-PKTX delivers the reliability and precision required for dependable communication between PCs and Allen-Bradley legacy networks.
