Description Model EN35V is a low-cost 3½ digit (±1999 count) digital voltmeter accepting DC voltages in four user-selectable ranges. This meter fits a standard 1/8 DIN cutout (92 mm x 45 mm) and is a direct replacement for Newport Model 201AN, with the exception of case length. 115 Vac power is provided standard, 230 Vac and 9-32Vdc power are available as options.
The signal input is true differential, bipolar, auto-zero and auto-polarity. Broad range user adjustable scaling from 20 to 1,999 counts is provided. Options include: T1 screw terminal barrier strip for signal and power, DC current measurement (20 µA to 200 mA in 5 ranges), and zero offset control. High quality construction and a conservative design makes this display the choice for industrial applications. A two-year warranty is standard.
