Rare Find Allen-bradley 1746-qv Open-loop Velocity Control Module Mega Pack [kBZDNqHp]

AB 1746-QV is an Open-Loop Velocity Control Module designed by Allen-Bradley, a Rockwell Automation brand, specifically for the SLC 500 programmable logic controller (PLC) system.

Purpose: It controls the speed (velocity) of an electric motor in an industrial automation application. However, unlike a closed-loop system, it doesn't rely on feedback to adjust speed in real-time.

Some key points about AB 1746-QV:
Open-Loop Control: It uses pre-programmed settings or external commands to control motor speed without continuously monitoring the actual speed.
Linear Displacement Transducer (LDT) Input: The module typically receives position data from a sensor called a Linear Displacement Transducer (LDT). This sensor can track the movement of a machine part.
Programming: The AB 1746-QV requires programming within the SLC 500 environment to define desired motor speeds and behaviors.
