Product Overview

The Allen Bradley 1784-PCIC operates as a high-speed, deterministic ControlNet network interface card designed for standard 32-bit PCI expansion slots inside Windows-based industrial computers. This communication card transforms a standard industrial PC into an active, intelligent ControlNet node, establishing a direct bridge for supervisory control, real-time data logging, and complete system monitoring. Industrial workstations utilize this card to execute full network configuration routines via RSNetWorx, pull real-time production analytics for SCADA applications, and exchange scheduled interlocking data with ControlLogix, PLC-5C, and SLC 500 processors. We offer this hard-to-find legacy component exclusively as a 100% brand-new, original Series A unit to guarantee absolute hardware timing compliance and reliable bus handshaking.

Engineering Advantages

Establishes True Deterministic Data Links: Unlike standard Ethernet cards that suffer from packet collision delays, this card locks onto the fixed ControlNet Nut (Network Update Time) interval. This precise physical clock synchronization guarantees predictable data transit times for high-speed SCADA acquisition and coordinated machine control loops.
Simplifies Local Workstation Configuration: Onboard mechanical rotary switches allow hardware engineers to dial in the target node address directly onto the card frame before sliding it into the motherboard slot. This standalone physical addressing system eliminates complex software driver sequencing and prevents address assignment losses during operating system reboots.
Eliminates External Signal Isolation Hardware: The card features dual BNC coaxial connectors that interface directly with standard ControlNet taps (such as the 1786-TPS). This native matching design preserves network impedance tracking, isolates industrial PC electronic noise from the field lines, and supports redundant media cabling layouts.
Streamlines Plant-Floor Diagnostics: Dual external-facing LED clusters provide immediate visual status updates regarding the internal module health and active network token status. This allows maintenance technicians to isolate PC-side motherboard faults from field trunk line breaks instantly without booting up troubleshooting software.

FAQs

Can I insert the 1784-PCIC card into a modern PCI Express (PCIe) slot?

No. The 1784-PCIC features a traditional legacy 32-bit edge connector that requires a standard, physical 5V PCI slot on your industrial computer motherboard. It will not fit or operate inside physical PCIe (x1, x4, x8, or x16) lanes. If your modern host PC only provides PCIe slots, you must utilize a 1784-PCIE card or deploy an external bridging mechanism.
Does this brand-new card require an external power supply connection inside the PC case?

No. The card draws all necessary operational current directly from the host computer motherboard through the gold contact fingers of the 32-bit PCI slot. It requires no auxiliary molex or SATA power drops from the computer power supply unit.
What software utility do I need to map network tags through this interface card?

You must install Allen Bradley RSLinx Classic (version 2.x or later compatible with your Windows OS platform) to establish the primary hardware driver communication link. To configure scheduled network update times and I/O traffic parameters across the trunk line, you will need RSNetWorx for ControlNet software.
