Metering Devices
If zero time delay is
programmed, any disturbance
lasting two cycles (less if
magnitude is sufficient to
effect rms readings) will
trigger a voltage disturbance
event/alarm.

(except Voltage Disturbances
—programmable from
2–3600 cycles in two-cycle
increments, and Eaton’s
Power Management
Software commands—no
programmable delay).

Input/Output
Extensive input/output
capability is standard on the
IQ Analyzer. In addition to
monitoring three-phase
currents and voltages,
separate inputs
are provided
for both ground and neutral
currents. Voltage of neutral-
to-ground is also monitored to
indicate the presence of
harmonics and potential
downstream grounding
problems. Analog and digital
I/O provide interfaces for
transducers, relays, PLCs
and control systems.
Current Inputs
Five ampere secondary CT
connections for:
●
Phases A, B, C
●
Ground
●
Neutral
●
Separate ground and
neutral CT inputs
●
CT range 5:5–10,000: 5
(any integer)
Voltage Inputs
●
Phases A, B, C (from
120 Vac–500 kV AC)
●
120/240 Vac control power
input standard—not
required with optional line
power module
●
Separate ground-to-neutral
voltage reference
●
PT range 120:120–
500,000:120 (any integer)
External 120-volt secondary
PTs are required above
600 Vac, optional from
120–600 Vac.
Discrete Contact Inputs
Three dry contact discrete
inputs may be programmed
by the user to:
●
Trigger Event Analysis—
the information described
in “Event Analysis
Screens,” including
Harmonic Analysis
information, can be
recorded when external
devices trip or change state
by wiring their auxiliary
contacts into these inputs
●
Act as a synch.-pulse
input to synchronize
power demand windows
with utility provided
synch. pulse
●
Actuate a relay output
●
Reset relay output, peak
demands, Trend Analysis
records and Event
Analysis records
●
With communications
option, provide remote
status indication on Eaton’s
communication network
●
Status of input contacts is
displayed in the Meter
Menu Custom screen
Relay Output Contacts
Four Form-C (NO/NC)
relay contacts may
be independently
programmed to:
●
Act as a kWh, kVARh or
kVAh pulse initiator output
●
Actuate on one or more
event conditions—including
discrete input software
commands (through
communications port)
●
Reverse sequence alarm
Each relay may be set for
Auto or Manual Reset with
0–30 minute release delay
(one second increments).
Relays are Form-C NO/NC.
Relay(s) programmed to
actuate on undervoltage
also have a programmable
0–30 minute delay on power-
up for transfer applications.
Analog Input and Outputs
One analog input and four
analog outputs may be
configured as 0–20 or
4–20 mA. The analog input is
displayed at the device as a
percentage and is accessible
through the communications
port. The analog input
provides an interface with gas
flow meters, temperature
transducers or other analog
devices.
The analog outputs may be
programmed
to reflect any of
the following:
●
Current—Phases A, B, C,
Average, N, G
●
Voltage—L-L, L-N, N-G
●
