Description

The DIS471B-R provides a display proportional to a DC input signal. Span of the input is selected by a moveable jumper on the rear of the housing. The display controls are wide-ranging so that it can be calibrated to display engineering units. A complete set of engineering unit labels is sent with each DIS.

All controls for calibration of the display are accessible by removing a gasketed front access panel. DIS instruments are gasketed and, when properly installed, are NEMA-4 rated for being waterproof.

Terminations are made to a screw terminal connector on the rear of the case.

Typical Applications

Monitor a process DC voltage or current and indicate the value of the the process measurement in appropriate engineering units.

Mounting

The DIS471B-R 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 DIS471B-R to the panel from the front.
