The Allen-Bradley 1746-QV is a specialized motion control module designed for the SLC 500 platform, specifically engineered for open-loop velocity control. This module is primarily utilized to manage the speed and positioning of hydraulic rams or pneumatic actuators. By integrating feedback from a Linear Displacement Transducer (LDT) and executing motion profiles directly from the SLC processor, the 1746-QV provides a cost-effective alternative to full closed-loop servo systems while maintaining smooth, profiled motion control.
The 1746-QV is ideally suited for industrial machinery requiring controlled hydraulic movement, including die casting machines, industrial welders, and non-CNC hydraulic presses. It is designed for applications where precise speed ramping is required to improve cycle times and reduce equipment stress.

No, the 1746-QV is specifically designed for open-loop velocity control. It is intended for applications that require profiled motion without the complexity of full closed-loop servo synchronization.
The module supports the configuration of up to seven (7) different voltage levels for each motion profile, allowing for granular control over acceleration and deceleration phases.
Our production line was down due to a faulty Bently Nevada monitor. We found it in stock here and they shipped it via DHL immediately. Back in operation within 48 hours—truly a lifesaver for our plant.
Finding brand new, original modules is critical for our safety. This team delivers factory-fresh components with full certification. Their commitment to only selling new products makes them our most trusted partner.
We have sourced Honeywell and Schneider parts here for two years. Every shipment arrives well-packaged with original factory seals intact. Clear communication and the best lead times in the industry.
