Description
Product Overview
The Woodhead APP-ETH-PCU PCU2000ETH is an industrial Ethernet-to-powerline communication gateway designed for harsh environment connectivity. As part of Woodhead’s (now Molex) ruggedized networking portfolio, this device enables data transmission over existing AC power lines, eliminating the need for additional communication wiring in industrial facilities. The PCU2000ETH operates on HomePlug 1.0 technology, providing 14 Mbps throughput with AES-128 encryption for secure machine-to-machine communication. Its IP67-rated aluminum housing withstands vibration, moisture, and extreme temperatures common in manufacturing plants and outdoor installations. The gateway features auto-negotiating 10/100Base-TX ports with M12 connectors for reliable Ethernet connectivity, while integrated powerline coupling requires no additional filters. For industries retrofitting legacy equipment with IIoT capabilities, the Woodhead APP-ETH-PCU PCU2000ETH delivers a cost-effective alternative to wireless or conduit-based solutions, particularly in metal-rich environments where RF signals face challenges.
