Model 201AN is a low-cost 3 1/2 digit DC voltmeter. Fits in a standard 1/8 DIN panel cutout and require a depth of less than 4.1 in (104 mm) behind the panel. With the addition of a screw-terminal barrier strip, it becomes a low-cost, pin-compatible alternative to the Q2000A and Q2000B in applications where indication-only is required.

Input Ranges
The 201AN offer voltage ranges of ±0.1999 V, ±1.999 V, ±19.99 V and ±199.9 V dc. The input is true-differential, with excellent common-mode noise rejection (CMR). By using an external DC voltage reference, any of these ranges can further be configured for 3-wire ratio measurement with readout from 0 to 1.999.

Options
The 201AN can be configured for four voltage input ranges, three decimal-point positions, and high- impedance 3-wire ratio input. Mechanical options include a screw-terminal barrier strip for signal and power and a splash-proof lens cover which meets NEMA-4 standards.
