Description
Description
The DP301AN is a low-cost 3-1/2 digit DC voltmeter. It fits ina standard 1/8 DIN panel cutout and require a depthof less than 104 mm (4.1") behind the panel. With theaddition of a screw-terminal barrier strip, it becomes alow-cost, pin-compatible alternative to the DP2000Aand DP2000B in applications where indication-onlyis required.
INPUT RANGES
The DP301AN offer voltage ranges of±0.1999V, ±1.999V, ±19.99V and ±199.9 Vdc. Theinput is true-differential, with excellent common-modenoise rejection (CMR). By using an external DCvoltage reference, any of these ranges can further beconfigured for 3-wire ratio measurement with readoutfrom 0 to 1.999.
OPTIONS
The DP301AN can be configured for fourvoltage input ranges, three decimal-point positions,and high-impedance 3-wire ratio input. Mechanicaloptions include a screw-terminal barrier strip for signaland power and a splash-proof lens cover which meetsNEMA 4 (IP65) standards.
