Description

The DIS471 provides a display proportional to a DC input signal.  The unit includes filtering and conditioning to reduce susceptibility to transients and noisy operations. The digital display utilizes an auto-zero dual-slope integrating A/D converter for accuracy and stability.

All DIS instruments are gasketed and, when properly installed, are NEMA-4X waterproof and corrosion resistant. ZERO and SPAN controls are accessible by removing a 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, accessible from the rear.

A complete set of engineering unit labels is sent with each DIS.  Terminations are made to a screw terminal connector on the rear of the case.

Typical Applications

DC voltage, current and process indication.

Mounting

The DIS471 is designed to be mounted from the front panel through a standard horizontal 3.62 X 1.77 inches (1/8 DIN) cutout. Two mounting cam-screws allow the securing of the DIS471 to the panel from the front.
