Low-Profile 1?16 DIN Case
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.
