Molex APP-ETH-PCU-C（PCU2000ETH）是原Woodhead Applicom系列PCI总线独立工业以太网通讯卡，搭载AMD SC520独立通讯处理器，板载16MB内存与4MB闪存，自带固件协议栈，不占用主机CPU算力，专门用于上位机和自动化控制器之间的数据交互。

Molex APP-ETH-PCU-C (PCU2000ETH) is an Applicom PCI Ethernet card inherited from Woodhead. Equipped with AMD SC520 processor, 16MB SDRAM and 4MB Flash, it runs protocol stack locally and relieves host CPU load for stable industrial data communication between PC and automation controllers.

支持10/100Mbps自适应RJ45以太网接口，PCI/PCI-X通用插槽（3.3V/5V兼容），配套Applicom驱动、DAServer、OPC接口，广泛适配Wonderware等SCADA/HMI平台。该型号已停产，存量备件多用于电厂、化工老上位机系统通讯卡替换维保。

It supports 10/100Mbps auto-negotiation RJ45 port, universal PCI/PCI-X 3.3V/5V slot. Compatible with Applicom driver, DAServer and OPC for Wonderware SCADA. This card is discontinued, used as legacy spare for old SCADA workstation maintenance in power and chemical plants.
