The 1771-QB is a linear positioning module manufactured by Allen-Bradley and designed under the standards of the 1771 series. This module is a dual-loop position controller that functions in a simple slot in the Allen-Bradley 1771 chassis. This module has the ability to control the servo, hydraulic, or electrode servos and it can be used to control and monitor the linear position of another machine or tool on one or two axes. The position is measured with a linear displacement transducer. The Allen-Bradley 1771-QB linear positioning module requires an input external power of 15 Volts DC minimum and 24 Volts DC minimum at 50 milliamps maximum. It has a thermal dissipation of 12.0 to 18.0 watts and a velocity of 3276.7 millimeters per second. The environmental conditions for the Allen-Bradley 1771-QB linear positioning module are an operating temperature of 0 to 60 degrees Celsius and a relative humidity of 5 to 95 percent.

The Allen-Bradley 1771-QB linear positioning module has three indicators, Loop 1 Active and Loop 2 Active, which are two green indicators that are on when each loop is active, and a Fault indicator, that lights up when there is a fault in one or both loops. This indicator is usually off. When installing or dealing with spare parts of the Allen-Bradley 1771-QB linear positioning module, it is important to maintain a workplace that is static-free, since electrostatic discharge can degrade the performance or damage some parts of the module. It is also important to include the module on a grounded system in order to prevent, electromagnetic interference.
