Description
Description
The DP3520 is an economical 5-volt powered,high-resolution, high-accuracy 4-1/2 digit DC voltmeterin a compact 1/16 DIN case. The height of the panelcutout is only 22 mm (0.88"). The depth behind thepanel is only 72 mm (2.83").
Low cost, small size, low power consumption andexceptional power-supply noise rejection make theDP3520 ideal for demanding OEM and portableinstrumentapplications. Non-isolated character-serialBCD output is standard to allow the DP3520 to beinterfaced to other instrumentation.
PARALLEL BCD OPTION F2M
The F2M option is an upper board whichconverts the meter’s serial BCD output tonon-isolated, three-state parallel BCD. An addressdecoder on the board permits the meter’s parallelBCD outputs to be enabled by a 4-bit binary addresssignal for three-state data-busing applications.
Options:- Three-State Parallel BCD Output
- High-Impedance 3-Wire Ratio Input
