الوصف
As an industrial automation expert, the ALSTOM MVTU11K1CD0751G is an Auxiliary Variable Speed Relay from Alstom. While Alstom is now primarily known for its rail transport and power generation solutions, they also produced industrial control components, particularly for their power and industrial automation systems.
This specific part is a type of relay that plays a role in control systems, likely related to equipment where variable speed is a factor. The “auxiliary” nature suggests it works in conjunction with primary control devices, providing additional logic, interlocking, or status indications.
Based on available information, key aspects of the MVTU11K1CD0751G include:
Features and Functionality
- Auxiliary Relay: As an auxiliary relay, it’s designed to perform secondary control functions. This could involve:
- Signal Amplification: Boosting a weak control signal.
- Isolation: Providing electrical isolation between different parts of a control circuit.
- Logic Functions: Implementing simple ON/OFF logic, interlocking, or sequencing.
- Status Indication: Providing feedback on the state of a process or piece of equipment.
- Memory Functionality: Some auxiliary relays, particularly “battery backup/latch auxiliary relays,” can retain their state even after a power failure and reproduce it upon re-powering. This is crucial for maintaining a system’s memory of instantaneous conditions.
- Variable Speed Application: The “variable speed” in its designation strongly suggests its use in systems that involve motors, pumps, fans, or conveyors where speed control is essential. It might monitor speed thresholds, provide interlocking based on speed, or enable/disable components depending on the operational speed of machinery.
- Integration with PLCs/Control Systems: While a relay itself, it’s highly likely designed to integrate with larger PLC (Programmable Logic Controller) or DCS (Distributed Control System) environments. It could be controlled by PLC outputs or provide inputs to a PLC, extending the control logic or handling specific electrical loads.
- Industrial Reliability: As an Alstom component for industrial use, it would be built to withstand typical industrial environments, including variations in temperature, humidity, and electrical noise.
Technical Specifications (General based on relay type)
Specific, detailed technical specifications for this exact part number are not widely published. However, based on its function as an industrial auxiliary relay, typical specifications would include:
Typical Applications
The ALSTOM MVTU11K1CD0751G would be found in industrial control circuits, particularly those that involve:
- Conveyor Systems: For interlocking based on conveyor speed, preventing startups if speed conditions aren’t met, or managing material flow. For instance, a conveyor might not start after a power failure unless a specific condition is met, which could be handled by a latching auxiliary relay.
- Pumps and Fans: Monitoring and controlling operations based on motor speed, such as enabling lubrication systems only when a certain RPM is reached.
- Process Control: In older Distributed Control Systems (DCS) or PLC setups where Alstom components were used for specific logic or interface requirements.
- Power Generation and Distribution: Given Alstom’s heritage, it could be used in switchgear control, protective relay schemes, or auxiliary controls within power plants.
- Railway Systems: Alstom’s core business, so it’s plausible to find these in auxiliary control circuits of locomotives or signaling systems, especially for components with variable speed elements.
Important Note on Lifecycle
Like many specialized industrial components, the ALSTOM MVTU11K1CD0751G is very likely a discontinued or legacy product from Alstom’s earlier industrial automation portfolio. If you’re seeking this part, you’ll probably need to look to:
- Industrial surplus suppliers
- Specialized industrial repair services
- Brokers of obsolete industrial parts
