• Event recorder for logging internal diagnostics events, control events
and I/O operations.
• Eight Fast Waveform recorders: 57-channel simultaneous recording
with 8 AC, one VDC and 48 digital input channels; optional 41-
channel recording with 8 AC, one VDC, 16 digital and 16 fast analog
input channels; selectable AC sampling rate of 32, 64 or 128 samples
per cycle; 20 pre-fault cycles, 1-ms resolution for digital inputs; up to
3 min of continuous recording with a 4-Mbyte onboard memory at a
rate of 32 samples per cycle; synchronized waveforms from multiple
devices in a single plot ; exporting waveforms in COMTRADE and
PQDIF file formats.
• Sixteen Fast Data recorders: 1/2-cycle to 2-hour RMS envelopes; up
to 20 pre-fault and post-fault cycles; programmable data logs on a
periodic basis and on any internal and external trigger; triggering
from the Fault recorder, PQ recorder or control setpoints; exporting
data trends in PQDIF file format.
