Description
Product overview
The Woodhead APP-ETH-PCU-C PCU2000ETH provides Ethernet connectivity between industrial devices and computer-based control or monitoring applications. Unlike a standard consumer network adapter, this Applicom card includes onboard processing and supports industrial communication software interfaces used for data acquisition and supervisory systems. It was designed for applications in which PLCs and other Ethernet-connected devices exchange data with HMI, SCADA, or other PC-based software.
The card uses a Universal PCI host interface and a single 10/100 Mbps Ethernet port. Its AMD SC520 processor, 16 MB SDRAM, and 4 MB flash memory are documented in the Applicom product literature. Software and driver compatibility should be checked carefully when moving the card into a replacement computer, especially where a modern operating system or motherboard is involved. A physically compatible slot alone does not guarantee that the required driver, application interface, or protocol package will work.
For maintenance and replacement procurement, the APP-ETH-PCU-C designation should be matched against the card label and the host system’s existing configuration. The Ethernet-only PCU2000ETH differs from related Applicom cards that combine Ethernet with PROFIBUS or serial communication. Before ordering, verify the exact order number, PCI form factor, software interface requirements, and installed driver version. For used inventory, request a functional test that confirms operating-system detection, Ethernet link status, and communication with a compatible device or test setup.
Product introduction
The APP-ETH-PCU-C is an older Applicom Ethernet interface for industrial PCs. Its purpose is to connect host software with Ethernet-based automation equipment through a dedicated network card and compatible communication drivers.
The main replacement risk is software and hardware compatibility, not just the card’s physical condition. Verify the PCI slot, operating system, installed Applicom software, and required protocols before replacing an existing card.

Frequently asked questions
Q1: What is the APP-ETH-PCU-C PCU2000ETH used for?
It provides Ethernet connectivity between industrial devices and PC-based applications such as HMI, SCADA, and data acquisition systems.
Q2: Is the PCU2000ETH a PCI Express card?
No. The APP-ETH-PCU-C uses Universal PCI. The APP-ETH-PCIE is the related PCI Express model and has a different host interface.
Q3: What Ethernet speed does it support?
Manufacturer documentation specifies 10/100 Mbps Ethernet with auto-negotiation through one RJ45 port.
Q4: Will it work in a modern industrial PC?
Not automatically. Check the motherboard’s available PCI slot, operating-system support, driver availability, and compatibility with the existing Applicom software and protocol configuration.
Q5: Does this model include PROFIBUS or serial ports?
The APP-ETH-PCU-C is the Ethernet-only version. Applicom offered separate models combining Ethernet with PROFIBUS or serial interfaces.
Q6: What should be included in a supplier’s test report?
Request confirmation that the card is recognized by a compatible host, the Ethernet link operates, and data communication succeeds with a compatible device or test environment. Ask the supplier to identify the tested operating system and driver version.
Q7: What should be checked before purchase?
Verify the exact model and order number, PCI interface, board condition, Ethernet connector, driver package, and compatibility with the existing host computer and application.
Procurement recommendation
For the Woodhead / Molex APP-ETH-PCU-C PCU2000ETH, prioritize the exact PCI version and software compatibility. Confirm that the card is the Ethernet-only 112000-0005 variant, rather than the PCI Express or Ethernet-plus-fieldbus versions.
For a used or surplus card, request actual photographs, confirmation of the order number, and a test report showing host recognition and successful Ethernet communication. If the card is supporting a legacy SCADA or HMI installation, verify driver and application compatibility before removing the existing hardware.
