Introducing the Linear Positioning Module
The Linear Positioning Module (Cat. No. 1771-QB) is a dual-loop position
controller occupying a single slot in the Allen-Bradley 1771 Universal I/O
chassis. It can control servo or proportional hydraulic valves, or some electric
servos. Position is measured with a linear displacement transducer. You use the
module to control and monitor the linear position of a tool or workpiece along
one or two axes.
