GE IS420ESWBH3A Power Sensing Board

Description

The GE IS420ESWBH3A is a high-performance, unmanaged 8-port Ethernet switch designed specifically for the PACSystems Mark VIe control system. While often grouped with sensing modules in a rack, this "ESWB" (Ethernet SWitch Board) serves as the communication backbone for the IONet, facilitating real-time data exchange between controllers, I/O packs, and other networked industrial devices.

Specifications

• Port Configuration: 8 unmanaged 10/100 Base-TX copper ports
• Input Power: 28 VDC nominal (typically supplied via the Mark VIe power distribution)
• Operating Temperature: -30 to +65 °C (-22 to +149 °F)
• Data Rate: 10/100 Mbps auto-negotiation per port
• Enclosure Rating: IP20 / Open type for cabinet mounting
• Communication Protocol: Optimized for GE IONet real-time industrial Ethernet
• Indicator LEDs: Discrete lights for Link/Activity status and Speed identification

Features

• Industrial Hardening: Engineered to operate reliably in environments with high electromagnetic interference and extreme temperature fluctuations common in power plants.
• Plug-and-Play Simplicity: Requires no software configuration or IP address management, allowing for immediate "out-of-the-box" deployment within the control network.
• Zero-Configuration Latency: Designed for low-latency packet forwarding to ensure deterministic performance for critical control signals.
• Redundant Power Capability: Supports integration into redundant power schemes to prevent network failure during a single power supply loss.
• Compact Footprint: Features a slim design that maximizes space efficiency within the GE Mark VIe control cabinet or on standard DIN rails.
