The Ultra SlimPak G408-1000 is a DIN rail mount, DC input signal conditioner with 1800Vdc isolation
between input, output and power. The field configurable input and output offers flexible, wide ranging
capability for DC current and voltage signals.
The input of the G408-1000 Ultra SlimPak can be configured for any one of 12 voltage ranges from 10mV to
100V or 6 current ranges from 1mA to 100mA (see table 1). The output is linear to the input and can be set
for -5V to +5V or -10 to +10V.
Wide ranging, precision zero and span pots allow 50% adjustability of offset and span turn-down within each
of the 18 switch selectable ranges. For example, the 0-2mA input range could be turned down to 0-1mA
and provide a full scale output signal (e.g. -10 to +10V), or turned down and offset to achieve a
1-2mA/-10 to +10V I/O combination.
The G408-1000 also accepts bipolar inputs (e.g. 10V range set to bipolar = -10 to +10V) and offers
selectable normal, or reverse operation (e.g. 4-20mA/+10 to -10V). The ASIC based I/O channel is optically
isolated to 1800Vdc and is transformer isolated from the power supply.
The Ultra SlimPak G408-1000 field configurable isolator is useful in eliminating ground loops, converting
signal levels, and providing signal drive. The field configurable, wide ranging capability ensures maximum
flexibility for most DC to DC applications, minimizing spare part requirements.
The G408-1000 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 flash at 8Hz. Below -10%, the flash rate
is 4Hz.
