1GENERALDESCRIPTIONANDSPECIFICATIONS

The Model 10A60-4 is a general-purpose conditioner allowing input of up to four

external voltage signals. Mixed as desired, these may originate from DC-to-DC

LVDT’s, potentiometer-type sensors, and other 2-wire analog signal sources that

pro-

vide their own power supply.

Or they may represent the outputs of other instrument

systems having various voltage levels and grounding configurations.

Inputs can be either floating (differential) or grounded (single-ended). With differential

inputs, generous common-mode range and excellent common-mode rejection elimi-

nate ground-coupling errors and other problems normally associated with off-ground

signal sources. Chopper-stabilized DC amplification with active low-pass filtering

yields smooth and stable measurement of the true average value of the input variable,

even in the face of substantial dynamic content.

Transducer Types

: 2-wire DC voltage sources, grounded or floating

Input Voltage Ranges: ±0.5, 1.0, 2.0, 5.0, 10, or 20 V-DC; automatically selected—on

an individual channel basis—when the channel is configured; for the System 10

channel “type” codes assigned to 10A60-4 data channels, see Table 1, below

Amplifier (per channel):

Common-Mode Range: ±50 V operating; ±300 V without instrument damage

Common-Mode Rejection Ratio: DC: -60 dB; at 60 Hz: -70 dB

Input Impedance: Differential: 2 MΩ; Common-Mode: 0.5 MΩ

Offset: Initial: ±0.5 mV; vs. Temperature: ±0.005 mV/°C; vs. Time: ±0.05 mV/month

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

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

Filter (per channel):3-pole modified Butterworth; 3 dB down at 10 Hz; 60 dB down at

100 Hz

Auxiliary Outputs: Filtered outputs available on mainframe wire-wrap pins

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

could occur upon replacement of a Model 10A60-4 not followed by calibrationis ±3% of full

scale.
