1GENERALDESCRIPTIONANDSPECIFICATIONS

The Model 10A63-2 is a high-accuracy conditioner allowing input of one or two exter-

nal voltage signals

. Mixed as desired, these may originate from DC-to-DC LVDT’s,

potentiometer-type sensors, and other 2-, 3-, or 4-wire analog signal sources, either

grounded or floating—or they may represent the outputs of other instrument systems

having various voltage levels and grounding configurations.

The 10A63-2 offers a wide range of input voltages. Its differential inputs, generous

common-mode range, and excellent common-mode rejection eliminate ground-cou-

pling errors and other problems normally associated with off-ground signal sources.

Nominal 5 V-DC excitation is provided for external sources that require it. “1/2 Bridge

Completion” terminals allow “zero-center” operation of potentiometers with resistance

from 1 to 10 kΩ.

Transducer Types

: 2-, 3-, or 4-wire DC voltage sources, grounded or floating

Input Voltage Ranges: ±0.05, 0.1, 0.2, 0.5, 1, 2, 5, 10, 20, 50, 100, or 200 V-DC; auto-

matically selected—on an individual channel basis—when the channel is configured;

for the System 10 channel “type” codes assigned to 10A63-2 data channels, see

Table 1, below

Excitation (per channel): Nominal 5 V-DC; 50 mA, maximum

Amplifier (per channel):

Normal-Mode Range: ±200 V operating; ±500 V without instrument damage

Common-Mode Range: ±200 V operating; ±300 V without instrument damage

Common-Mode Rejection Ratio: DC: -120 dB; at 60 Hz: -60 dB

Input Impedance: Differential: 1 MΩ; Common-Mode: 0.5 MΩ

Offset: Initial: ±0.02% of full scale; vs. Temperature: ±50 ppm/°C; vs. Time: ±20

ppm/month

Gain Accuracy: ±0.02% of full scale typical, following calibration*

Gain Stability: vs. Temperature: ±50 ppm/°C; vs. Time: ±50 ppm/month

(cont’d)

*Initial (uncalibrated) inaccuracy may be as great as ±1.5% of full scale. Maximum error that

could occur upon replacement of a Model 10A63-2 not followed by calibrationis ±3% of full

scale.
