The DP301AN is a low-cost 3-1/2 digit DC voltmeter. It fits in
a standard 1/8 DIN panel cutout and require a depth
of less than 104 mm (4.1") behind the panel. With the
addition of a screw-terminal barrier strip, it becomes a
low-cost, pin-compatible alternative to the DP2000A
and DP2000B in applications where indication-only
is required.
INPUT RANGES
The DP301AN offer voltage ranges of
±0.1999V, ±1.999V, ±19.99V and ±199.9 Vdc. The
input is true-differential, with excellent common-mode
noise rejection (CMR). By using an external DC
voltage reference, any of these ranges can further be
configured for 3-wire ratio measurement with readout
from 0 to 1.999.
OPTIONS
The DP301AN can be configured for four
voltage input ranges, three decimal-point positions,
and high-impedance 3-wire ratio input. Mechanical
options include a screw-terminal barrier strip for signal
and power and a splash-proof lens cover which meets
NEMA 4 (IP65) standards.
