Description
The G478 is a DIN rail mount,
frequency input signal conditioner
with 1800VDC isolation between
input, output and power. The
field configurable input and
output offer flexible, wide
ranging capability for variable
frequency drives, magnetic pick-ups,
turbine flow meters, and other
pulse or frequency output transducers.
The
input of the G478 can be configured
for any frequency span from
2Hz to 10,000Hz. The input amplitude
threshold sensitivity can be
adjusted from 150mVp to 10Vp
to ensure accurate frequency
measurement and minimize transient
noise related errors. The maximum
input amplitude is 150 Vrms.
The output can be set for 0-5V,
0-10V, 0-1mA, 0-20mA or 4-20mA.
The
G478 to be field configured
for virtually any frequency
input to DC signal output within
the ranges specified. Calibration
utilizes 'Touch-Cal' technology
in which the user simply applies
the minimum and maximum input
frequencies, and touches a re-
cessed button to configure the
corresponding minimum and maximum
output range.
The
Ultra SlimPak housing allows
installation of up to 24 units
per linear foot. The wide ranging
power supply is inverter isolated
and accepts any voltage between
9 and 30VDC.

Application
The G478 is useful in eliminating
ground loops and interfacing
pulse output transducers, such
as turbine flow meters and mag-
netic pick-ups, to data acquisition
and control systems.
Advanced
digital technology, combined
with Action's ASIC technol-
ogy, provide a stable output
at low frequencies for higher
accuracy.
