Nexus Overview

2.1: The Nexus System

Electro Industries’ Nexus 1250/1252 combines high-end revenue metering with sophisticated power quality analysis. Its advanced monitoring capabilities provide detailed and precise pictures of any metered point within a distribution network. The P60N, P40N, P41N and P43N displays are detailed in Chapter 6. Extensive I/O capability is available in conjunction with all metering functions. The optional Communicator EXT software allows a user to poll and gather data from multiple Nexus meters installed at local or remote locations (see the Communicator EXT User Manual for details). On board mass memory enables the Nexus to retrieve and store multiple logs. The Nexus Meter with Internal Modem (or Network) Option connects to a PC via standard phone line (or MODBUS/TCP) and a daisy chain of Nexus Meters via an RS-485 connection. See Chapters 10 and 11 for details.
