Description The Ultra SlimPak G438 is a DIN rali mount, potentiometer input signal conditioner with 1800Vdc isolation

between DC power and the input/output circuitry. The input provides a constant voltage and is designed to
accept any three-wire potentiometer from 100M to 100KM. The field configurable output is switch selectable
providing either 0-5V, 0-10V, 0-1mA, 0-20mA or 4-20mA DC signal.
Wide ranging, precision zero and span pots, used in conjunction with DIP switches, allow 80% adjustability
of offset and gain to transmit a full scale output from any 20% portion of the potentiometer input.

The Ultra SlimPak G438 field configurable, potentiometer input signal conditioner is useful in transmitting
process control setpoints to remote PID controllers or interfacing position sensors to data acquisition and
control systems.
The G438's high density DIN rail mounting offers an extremely compact solution for saving valuable panel
space.
