Application Fields
The NE802 is widely deployed in power generation, water treatment, and pulp and paper industries. It is specifically optimized for use in distributed control system (DCS) cabinets where electromagnetic interference (EMI) is high. Its primary role is to manage the “Plant Network” or “Control Network” layers, connecting various AC 800M controllers or similar hardware to the wider plant infrastructure.
Product Instructions
For proper installation, snap the NE802 onto a standard 35mm DIN rail within a grounded metallic enclosure. Connect the primary and redundant 24V DC power sources to the terminal block to ensure the switch remains active even if one power supply fails. Use Category 5e or higher shielded twisted pair (STP) cables for all network connections to maintain signal integrity. The module is “plug-and-play” for basic switching functions, but advanced VLAN or redundancy management should be configured via the ABB Network Configuration Tool.
Common Questions and Answers
Q: Does the NE802 support Ring Redundancy? A: Yes, it supports standard industrial redundancy protocols like MRP (Media Redundancy Protocol) and RSTP, allowing it to function in a ring topology with sub-millisecond recovery times.
Q: Can this switch be used in hazardous areas? A: The NE802 is designed with industrial-grade components that typically meet Class I Division 2 requirements, but you should verify the specific certification markings on the module label before installation in explosive atmospheres.
Q: Is the 3BSE080237R1 manageable or unmanaged? A: The NE802 is a managed switch, providing administrators with the ability to monitor port traffic, configure security settings, and manage network performance through a web-based interface or SNMP.
