The DIS871 and DIS971 provide a display, optional isolated DC output voltage or current proportional to a DC 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 the gasketed front access panel.
The display controls are wide-ranging so that it 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 transmitter output. Either setpoint may be displayed by use of the SP CAL switch. Each setpoint has an LED to indicate alarm status.
