The DIS873 and DIS973 provide a display, optional isolated DC output voltage or current proportional to an RTD input signal, and optional alarm setpoints. The units include filtering and conditioning to reduce susceptibility to transients and noisy operations.
All controls are accessible by removing a 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.
