Description

Application

Diagnostic LED

The field configurable G468 is a DIN rail mount, AC input signal conditioner with 1800Vdc isolation between
input, output and power. The field configurable input and output offers flexible, wide ranging capability for
scaling, converting or buffering AC inputs ranging from 5mA to 100mAac or 50mV to 250Vac.
For current inputs above 100mAac, it is recommended that an input shunt resistor be used and the G468
be configured for the proper input range. For example, a 5Aac current transformer output can use the
Action model C006 shunt resistor (0.1M, 5M) and set the input of the G468 for 0-500mVac.
The DC output of the G468 is proportional to the average of the fully-rectified AC input signal, and is
calibrated for sine waves between 40-400Hz.

The Ultra SlimPak G468 is useful in applications requiring an isolated, conditioned DC output from an AC
signal. Typical applications include energy management, load shedding, motor current/load monitoring,
locked rotor detection, isolation and data acquisition. The output of the G468 can drive a digital meter for
direct display or can interface with alarm or control devices including PLCs and computers.

The G468 is equipped with a dual function LED signal monitor. The green, front-mounted LED indicates
both DC power and input signal status. Active DC power is indicated by an illuminated LED. If the input
signal is more than 110% of the full-scale range, the LED will quickly flash at 8Hz. If this continues to occur,
you may wish to change your full-scale input range setting.
