DMS01-CL Series Large Format Digital Current-Loop Process Meter PRODUCT OVERVIEW DMS01-CL-RS12-C is a robust digital panel meter that provides precise measurement and display of current loop process signals on a highly visible red 1 (25mm) tall, 4 1/2 digit seven-segment LED display with adjustable brightness. It provides selectable 4-20 mA or 0-20 mA current range, up to 32 display ranges and choice of user calibration or factory calibration modes. An external 12VDC power source provides power to the meter. An internal DC-DC converter accommodates a +/-48V common- mode measurement range with respect to the power supply input, simplifying a wide range of measurement applications and an internal digital filter enhances performance in electrically noisy environments making this digital panel meter is ideal for laboratory instrumentation, factory automation, and any application requiring precision measurement.
