Description

The DP3520-PA is an economical 5-volt powered, high-resolution, high-accuracy 4-1/2 digit dc microvoltmeter in a compact 1/16 DIN case. The height of the panel cutout is 22 mm (0.88"), and the depth required behind the panel is only 72 mm (2.83").

Low cost, small size, low power consumption at 5 Vdc and exceptional power-supply noise rejection make the DP3520-PA ideal for demanding OEM and portable-instrument applications.

MICROVOLT PREAMPLIFIER
The DP3520-PA incorporates a preamplifier, which can be programmed for resolution from 1 to 25 µV/ count and for a zero offset up to ±0.6 mV (RTI) ±21% of full-scale readout (RTO).

The DP3520-PA can be configured for use with load cells and pressure gauges, which require zero and span adjustment for readout in engineering units. Bridge excitation may be provided by the same 5 Vdc supply that powers the meter, or by an external, isolated 10 or 15 Vdc power supply.

The DP3520-PA can also be configured as a microvoltmeter using an internal reference, or in a ratiometric mode using an external reference.

SERIAL BCD
Non-isolated, character-serial BCD output is standard to allow the DP3520-PA to be interfaced to other instrumentation.

Model DP3520-PA provides a differential programmable preamplifier for use with low-level bridge circuits. Bridge excitation can be provided by the same 5 Vdc power supply that powers the meter.
