The Allen-Bradley 1784-PKTX network interface card connects your computer directly to industrial control networks. This PCI 2.3 compliant module supports Data Highway Plus, Remote I/O, and DH-485 protocols. It allows process visualization and controller programming through a single host PC. The card mounts easily into any standard PCI slot.
Product Procurement & Buyer Guide
The 1784-PKTX solves a critical pain point for system integrators. It eliminates the need for a dedicated programming terminal for each network type. This single card provides three protocol connections from one PCI slot. You save money on additional hardware and reduce cabinet space.
This card communicates over long distances with flexible data rates. For DH+ and RIO networks, you get 10,000 ft. at 57.6K bit/s. At higher speeds, you still reach 5,000 ft. at 115.2K bit/s. The maximum speed of 230.4K bit/s covers 2,500 ft. This range suits large factory floor layouts perfectly.
The DH-485 channel provides a maximum cable length of 4,000 ft. It operates at speeds from 1200 to 19,200 bits/s. This flexibility allows connection to older SLC 5/01, 5/02, and 5/03 processors. You need a 1785-KA5 module to connect those controllers. The card supports up to four modules per system.
Procurement managers appreciate the rugged environmental specs. The module operates from 0 to 60°C with 5 to 95% non-condensing humidity. It withstands operational shock of 30G and vibration of 2G at 10 to 500 Hz. This durability ensures reliable performance in harsh industrial settings.
The card uses standard RSLinx PKTx drivers for easy setup. It connects to DH+ devices using a 10-foot CP12 cable with a 3-pin Phoenix connector. For DH-485 networks, you use the 1784-CP14 cable with a 6-pin Phoenix connector. Both cables include switchable termination resistors for proper network termination.
Step-by-Step User & Installation Guide
First, power down your host computer completely. Install the 1784-PKTX card into an available PCI 2.3 compliant slot. Secure the card bracket with the mounting screw. The card dimensions are 4.5 x 12.4 x 6.3 inches and it weighs only 0.3 lbs.
Next, connect your network cables to the correct channels. Use the 3-pin Phoenix connector on Channel 1A for DH+ or RIO networks. Use the 6-pin Phoenix connector on Channel 1C for DH-485 networks. Ensure the switchable termination resistor matches your network configuration.
Install the RSLinx PKTx driver software on your operating system. The driver recognizes the card and configures the communication channels. For non-standard operating systems, you must create a user-specific driver. The card provides one diagnostic LED per channel for status monitoring.
Configure the jumper settings to set the module ID. The system supports a maximum of four modules. Verify the jumper position matches your system requirements. The card does not require external power as it draws power from the PCI bus.
Test the connection by verifying communication with your PLC-5 or SLC processor. The card works with PLC-5, PLC-5/250, and SLC 5/04 processors directly. Check the status LEDs for proper link activity. A solid green LED indicates a healthy connection.
