1.0 DESCRIPTION

1.1 Introduction

The M87x family of monitoring and recording IEDs with SubCycle
breakthrough in power measurement technology.
expand the limits of range, speed, and accuracy of measurement, speed of
communications, and modularity. It combines a modular-by-board chassis featuring a
TM
CompactPCI card cage, with a dual processor measurement system featuring a 32-bit
floating point Digital Signal Processor (DSP) and a 486-based host processor.

1.2 Features

Extensive measurement set including two sets of voltages and currents with

corresponding power and energy on some models
Simultaneous support of multiple protocols over multiple physical links

Two completely independent Disturbance Recorders

Two separate Waveform Recorders

Trend Recorder

Sequence of Event log

Voltage Fluctuation Table to use for sag and swell reporting

Two options for analog inputs, 8 voltages with 4 currents and 2 auxiliary voltages or 8
