Description
Models EN35P and
EN35E are low cost, 3½ digit (±1,999
count) digital process meters accepting DC
voltage or current loops typically supplied by
process transducers. These meters fit a standard
1/8 DIN cutout (92 mm x 45 mm) and are direct
replacements for Newport Models 202A-P and
202A-E, with the exception of case length. 115
Vac power is provided standard, 230 Vac
and 9-32 Vdc power are available as options.
Broad-range scaling and zero offset allow these
meters to display directly in engineering units.
Decimal points, polarity (- or none) and LSD
on/off (display of 1,999 or 199) are selectable
by jumper on the display board.
Model EN35P is a
process indicator only, while model EN35E
provides the additional feature of DC excitation
voltage output. This output may be used to
provide transducer power in a two- or four-wire
configuration. High quality construction and
conservative design makes this display the
choice for industrial applications. A two-year
warranty is standard.
