OPTIONS ![]() ![]() ![]() ![]() Models 201A and 201AN are two pinout versions of the same low-cost 3 1/2 digit DC voltmeter. They fit 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, they become low-cost, pin-compatible alternatives to the Q2000A and Q2000B in applications where indication-only is required. INPUT RANGES The 201A and 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. TWO PINOUTS Model 201A is pin-compatible with Newport's older Model 201 and is recommended for existing 201 applications. Model 201AN is pin-compatible with Newport's new 202A, 2001A, 2002A Series and is recommended for new applications. OPTIONS The 201A and 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. SPECIFICATIONS ANALOG INPUT
