The DIS876 and DIS976 provide a display, optional isolated DC output voltage or current proportional to the slide position of a potentiometer, and optional alarm setpoints. The units include filtering and conditioning to reduce susceptibility to transients and noisy operations as well as a stable 1 V power supply to excite the potentiometer. Any value potentiometer from 100 ohms to 100 kilohms can be used.
All controls are accessible by removing the gasketed front access panel.
The display controls are wide-ranging so that they can be calibrated to display engineering units. Decimal point selection is made with a switch, also accessible from the front. Once the display has been adjusted to read the correct engineering units, the alarm setpoints can be adjusted without test equipment and without disturbing the output voltage or current. Either setpoint may be displayed by use of the SP CAL switch. Each setpoint has an LED to indicate alarm status.
