Allen-Bradley 1784-PCIC ControlNet PCI Card for Industrial Networks
The Allen-Bradley 1784-PCIC card provides a vital link between computers and ControlNet industrial networks. This universal PCI communication card fits standard computer expansion slots. It allows engineers to program, monitor, and control automated systems directly. The card delivers reliable data exchange for critical manufacturing processes. Its robust design meets the demands of harsh industrial environments.
Product Procurement & Buyer Guide
Procurement teams must verify slot compatibility for the 1784-PCIC card. This module works with 5 Volt and 3.3 Volt PCI slots. It also supports 32-bit, 64-bit, and PCI-X slots. This wide compatibility ensures integration into diverse host computers. Engineers should confirm a free slot exists before purchasing. The card’s dimensions are 4.2 by 6.5 inches. This compact size fits standard computer chassis without issue.
The card features dual network interface options for flexible deployment. An RJ45 connector links programming terminals to ControlNet devices. It also includes redundant BNC connectors for direct network attachment. This dual interface allows connection to either a network or a device. Only a 1786-CP cable should connect the terminal to the card. This specific cable ensures proper signal integrity and performance. Using the wrong cable can cause communication errors.

Power dissipation for this module is only 3.5 Watts. This low power draw reduces heat buildup inside the computer. The isolation voltage is 50 Volts, tested to 600 Volts for 60 seconds. This high isolation protects the computer from network voltage spikes. The working temperature range is 0 to 50 degrees Celsius. Storage and transport temperatures range from -40 to 85 degrees Celsius. These tolerances suit most factory floor conditions.
Installation requires careful handling to avoid electrostatic discharge damage. Users must touch a grounded object before touching the card. Grounded wrist straps and static-safe work areas are essential. Avoid touching card components, pins, or connectors directly. Store the card in a static-safe container when not in use. Following these steps ensures the card operates reliably for years.
The card holds certifications from CE, CSA, UR, EEx, and C-tick. These certifications confirm compliance with international safety and performance standards. Category 2 wire should be used for all communication ports. This wiring type meets the electrical requirements for ControlNet signals. The card’s robust construction ensures long service life in continuous operation.
Step-by-Step User & Installation Guide

Begin installation by completely shutting down the host computer. Remove the computer cover to access the internal expansion slots. Select a vacant slot that matches the card’s requirements. Remove the slot’s expansion cover to create an opening. Handle the card only by its edges to prevent ESD damage. Insert the card firmly into the slot until it is seated. Tighten the retaining screws to secure the card in place.
After installation, connect the card to the ControlNet network. Use the RJ45 connector for programming terminal connections. Use the BNC connectors for direct network attachment. Do not connect different ControlNet networks to the same card. Doing so can cause erratic communication system operation. The diagnostic LEDs on the card front provide status information. These LEDs only function when using the BNC connectors. They are meaningless when using the RJ45 port.
Connect the RJ45 port to a programming terminal using a 1786-CP cable. This connection allows software configuration and network monitoring. The card automatically interfaces with the ControlNet network after power-up. Verify network communication through the diagnostic indicators. The card’s low power dissipation keeps system temperatures stable. Follow all ESD precautions during every handling step. This ensures the card remains undamaged and fully functional.
