1GENERALDESCRIPTIONANDSPECIFICATIONS

The Model 10A64-8C is a high-accuracy conditioner allowing input of up to eight

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). 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.
