energy and demand registers for substation energy management,
accumulation of energy pulses from external watt-meters, block
and sliding demands, up to 64 energy sources)
•
Harmonic Analyzer (to 63rd harmonic volts and amps, directional
power harmonics and power factor, phasors, symmetrical
components)
•
32 digital counters for counting pulses from external sources and
numerous internal events
•

Additionally, the SA300 can be equipped with a 64/128-Mbyte Expansion Memory plug-in module for long-
term waveform recording.
AC/DC Inputs
The SA300 is provided with a set of fully isolated AC/DC inputs for a connection to the AC feeders and station
battery:
•
Four isolated AC voltage inputs (up to 690VAC direct line-to-line input voltage)
•
Four standard isolated AC current inputs with an extended input range up to
×3000%
overload (10A/IEC or 20A/ANSI input currents, to 150 Amps fault currents)
•
Optional second set of four isolated current inputs (10A/IEC or 20A/ANSI input currents)
for precise energy metering
•
DC voltage input (up to 300VDC) for monitoring the station battery
Digital and Analog I/O Options
The SA300 has five I/O expansion slots for removable plug-in I/O modules:

DI - Digital inputs (16 or 32 optically isolated inputs per module, up to 3 modules per
device; options for dry contacts, and wet inputs; programmable de-bounce time from 1
ms to 1 sec; free linkage to Sequence-of-Events Recorder, Fault Recorder, control
setpoints, pulse counters and Energy/TOU subsystem)
•
RO - Relay outputs (8 or 16 relays per module, up to 4 modules per device; unlatched,
latched and pulse operations, failsafe operation for alarm notifications; programmable
pulse width; direct remote relay control through communications)
•
