Wilkerson Instrument Co. DIS471 Process Indicator, a digital indicating system used for calibration controls. Function: It provides a digital display calibrated in engineering units (e.g., °F, °C, %, PSI) that are proportional to a DC input signal, such as 4-20mA DC. Features: It includes a 24 VDC power supply for two-wire transmitters, fits standard 1/8 DIN cutouts, and is rated NEMA-4 splashproof when properly installed. Power Requirements: It typically operates on 115V AC ±10%, 50/60Hz, with a maximum wattage rating of 4 watts. Calibration: ZERO and SPAN controls are accessible by removing a gasketed front access panel, and the display controls are wide-ranging, allowing calibration to display various engineering units.
