1784-PKTX | Allen-Bradley Communication Module

Introducing the Allen-Bradley 1784-PKTX Network Interface Card

Key Technical Specifications and Features

• Brand & Part Number: Allen-Bradley 1784-PKTX
• Communication Protocols: Data Highway Plus (DH+), Remote I/O (RIO), and DH-485
• PCI Compliance: The card is PCI 2.3 compliant for broad compatibility.
• Channel Configuration: Channel 1A handles DH+/RIO, while Channel 1C manages DH-485.
• Data Rates (DH+/RIO): Achieve 57.6K bit/s up to 10,000 ft, 115.2K bit/s up to 5,000 ft, and 230.4K bit/s up to 2,500 ft.
• Data Rates (DH-485): Operates up to 4,000 ft at speeds of 1200 to 19,200 bits/s.
• Environmental Tolerance: Functions in 0 to 60°C, withstands 30G shock and 2G vibration at 10-500 Hz.

Supported Controllers and System Integration

• The 1784-PKTX directly interfaces with PLC-5, PLC-5/250, and SLC 5/04 processors.
• It connects to SLC 5/01, 5/02, and 5/03 processors via a 1785-KA5 module.
• This network interface card supports Remote I/O scanner functionality for flexible system design.
• A single system can accommodate up to four 1784-PKTX modules.
• Each channel features a dedicated diagnostic/status LED for easy troubleshooting.

Hardware and Connectivity Details

• The card uses a 3-pin Phoenix connector for Channel 1A (DH+/RIO) and a 6-pin Phoenix for Channel 1C (DH-485).
• It requires no external power and includes a conformal coating for environmental protection.
• Typical AC and DC signal delays measure 29 (+/-8) ms and 30 (+/-7) ms respectively.
• Dimensions are 4.5 x 12.4 x 6.3 inches (115 x 317 x 160 mm), with a weight of just 0.3 lbs (0.1 kg).

Frequently Asked Questions (FAQ)

• Is the 1784-PKTX compatible with a modern PCIe slot?
  No, the 1784-PKTX specifically requires a PCI 2.3 compliant slot, not a PCIe slot.
• What is the maximum cable length for DH+ at 230.4K bit/s?
  At 230.4K bit/s, the maximum cable length is 2,500 feet (762 meters) on the DH+ network.
• Does this card work with SLC 500 processors on a DH-485 network?
  Yes, it connects to SLC 5/01, 5/02, and 5/03 processors on DH-485 using the 1784-CP14 cable.
• What is the operating temperature range for this module?
  The 1784-PKTX operates reliably in temperatures from 0 to 60 degrees Celsius (32 to 140 degrees Fahrenheit).
