1.0 DESCRIPTION
1.1 Introduction
The M87x family of monitoring and recording IEDs with SubCycle
TM
technology is a major
breakthrough in power measurement technology. The M87x IEDs were designed to
expand the limits of range, speed, and accuracy of measurement, speed of
communications, and modularity. It combines a modular-by-board chassis featuring a
CompactPCI
TM
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
voltages with 6 currents

128 samples per cycle, 16-bit sampling.

32-bit floating point DSP, capable of 180 MFLOPS (Million Floating Point Operations
Per Second). A 128-point complex Fast Fourier Transform (FFT) is performed in less
than 50 microseconds.

486-class Host processor.

Watchdog timer maximizes system reliability.

4 Configurable serial ports - Three RS232/RS485 ports/one DB9M Service RS232 port

Fully compatible CompactPCI
TM
backplane and system bus.

Rugged all-aluminum housing.

Choice of standard chassis (C07A5) with 3 option cPCI expansion bays, intermediate
chassis (C10A7) with 5 option bays or extended model (C12A8) with 6 option bays.

Option modules include digital I/O (P30A, P31 and P33), Ethernet (E1/E3, P10, P11,
P12), and transducer input (P40)

Split-core CT options (3 or 4 for M871, 6 for M872)

Optional detached display, D650 (replaced obsolete display M870D)
