1GENERALDESCRIPTIONANDSPECIFICATIONS
The Model 10A65-8 is a high-accuracy conditioner allowing input of up to eight low-
level external voltage signals
(allowable input ranges are ±50, ±100, and ±200 milli-
volts
). Mixed as desired, these may originate from DC-to-DC LVDT’s, potentiometer-
type sensors, and other 2-wire analog signal sources that
provide their own power
supply.
Or they may represent the outputs of other instrument systems having vari-
ous voltage levels and grounding configurations.
Inputs can be either floating (differential) or grounded (single-ended). Chopper-stabi-
lized DC amplification with active low-pass filtering yields smooth and stable measure-
ment of the true average value of the input variable, even in the face of substantial
dynamic content.
