11. QUADRATURE SIGNAL CONDITIONER BOARD

This signal conditioner can be used for quadrature position (Basic or Extended main board) or

for quadrature position and rate (Extended main board). Two quadrature signals, which are 90º

out of phase, are applied to the Channel A and B inputs. Their phase relationship determines

whether the count is clockwise (+) or counterclockwise (-). A zero index signal may be applied

to a Z Channel as a position reference.
