From Sep 1st 2018, DP520 Series will be discontinued. As a possible substitute, please check out the DPPt Meter or DP20 Meter for details.
The DP3520 is an economical 5-volt powered,
high-resolution, high-accuracy 4-1/2 digit DC voltmeter
in a compact 1/16 DIN case. The height of the panel
cutout is only 22 mm (0.88"). The depth behind the
panel is only 72 mm (2.83").
Low cost, small size, low power consumption and
exceptional power-supply noise rejection make the
DP3520 ideal for demanding OEM and portableinstrument
applications. Non-isolated character-serial
BCD output is standard to allow the DP3520 to be
interfaced to other instrumentation.
PARALLEL BCD OPTION F2M
The F2M option is an upper board which
converts the meter’s serial BCD output to
non-isolated, three-state parallel BCD. An address
decoder on the board permits the meter’s parallel
BCD outputs to be enabled by a 4-bit binary address
signal for three-state data-busing applications.
