G438-0001

Description
The G438 is a DIN rail mount, potentiometer input signal condi- tioner with 1800VDC isolation between input, output and power. The input provides a constant voltage and is designed to accept any three-wire potentiometer from 100 Ohms to 100K Ohms. The field configurable output is switch selectable providing either a 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% adjustablity of offset and gain to transmit a fullscale output from any 20% portion of the potenti- ometer input.

Application
The G438 is useful in transmitting process control setpoints to remote PID controllers or interfacing position sensors to data acquisition and control systems. The high density DIN rail mounting offers an extremely compact solution for saving valu- able panel space.

In a valve positioning application a potentiometer is sometimes used as a feedback signal. Quite often a wide open valve is only a 25% turn of the feedback potentiometer. In a case such as this, the G438 can easily be adjusted with the zero and span to provide a fullscale output signal (e.g. 4-20mA) representing 0-25% or even 50-75% of the potentiometer input.
