9251Fieldbus controller
Flexible, scalable and easy to integrate! The model 9251 fieldbus controller enables the cascading of up to 8 model 9250 measuring amplifiers with bus capability, while automatic detection and addressing make it easy to implement extensions. The controller can also be operated as a stand-alone device via the measurement input - for maximum versatility in measured value acquisition.

- EPLAN Macros 9251
The new 9250/9251 generation of amplifiers combines all the features that make modern data acquisition truly successful. Network-compatible, highly accurate, easy to operate, intelligent and customisable to any requirement, the system consisting of amplifier module and fieldbus controller can be integrated into any existing system.
The fieldbus controller delivers all signals exactly where they need to be combined, examined and linked. With the available fieldbus interfaces, you are flexible, perfectly cross-linked and save time, costs and additional resources when connecting and integrating into existing systems. Thanks to the integrated measurement input, the use of a fieldbus controller module is sufficient for single-channel applications. For multi-channel applications, the system can be extended to up to 9 measuring channels.
Up to 8 bus-capable model 9250 measuring amplifiers can be cascaded on the model 9251 fieldbus controller. Automatic detection and addressing of the measuring amplifier modules allows for easy expansion. The fieldbus controller can be operated as a stand-alone device using the measurement input.
In some applications, a large amount of measurement data has to be recorded and transmitted within a very short time. Therefor a very fast PLC communication is necessary with high update rates. To optimise the data throughput, the model 9251 fieldbus controller can transmit a complete data array with the last 32 measured values per channel. The scaled measured values are read simultaneously in the real-time data of the fieldbus connection.
- Multi-channel, universal measuring system consisting of up to 8 instrumentation amplifiers and a fieldbus controller
- Connection via PROFINET, EtherCAT or EtherNet/IP supports digital and fast measurement data acquisition in real time
- Highest flexibility due to a instrumentation amplifier for strain gauge, potentiometric, DC/DC and incremental sensors
Task
The poles of individual cells are welded in a vehicle battery assembly system. The poles of the up to 64 cells are connected with electrically conducting busbars using a laser welding procedure. In addition to a high degree of positioning accuracy a defined press-on force during the process must be 100 % guaranteed. In order to reduce the testing and cycle times, a force measurement is carried out at 8 poles in each case within the range of 400 to 500 N simultaneously. Measured value transmission takes place via 8 cascadable bus-capable instrumentation amplifier series 9250 and a PROFINET fieldbus controller model 9251 to a central control unit in real time.
Branchen
- Measuring ranges:
- Load: Fx = 1 kN / Fy = 1 kN / Fz = 2 kN
- Torque: Mx / My / Mz = 50 Nm - Low non-linearity from 0.1 % F.S.
- Customized axis configuration
- Robot flange according to DIN ISO 9049-1
Task
In a robot-controlled placement process, conclusions are to be drawn during the process about the correct parts, positioning and placement.
By means of a reference run, the forces and moments are recorded and serve as comparison parameters for the automated process. The distribution of the three forces and three torques provides information on completeness and alignment.
The placement process of workpiece carriers can be controlled, monitored and limited to maximum values, thus eliminating damage and rejects.
Branchen
- Measurement of press-in forces during an assembly process
- Precise determination of forces with the ring force sensor type 8438
- Multi-channel force measurement with up to 8 channels with one fieldbus interface
- EtherCAT, PROFINET and EtherNet/IP capable measuring system
Description
Battery trays must be carefully designed because they must protect the batteries, the heart of any electric vehicle, in the event of an accident. At the same time, it must be ensured that the battery trays can be opened if necessary, e.g. for maintenance of the battery cells. During the production of the battery trays, the bottom plate and the cover are connected by means of nuts. This connection must be secure, have guaranteed tightness, e.g. against dust, and be resistant to water pressure, as the battery cells are located in the space between them.
Special requirements
- High manufacturing quality of the battery trays
- Highest safety requirements
Solutions
Self-piercing nuts are used for the connection between the base plate and the cover. The press-fit process must have a 0-fault tolerance, which can be guaranteed with burster's process monitoring technology. The miniature ring force sensor 8438, which measures the press-in force, the potentiometric displacement sensor 8713, which determines the press-in displacement, and the combination of measuring amplifier 9250 and fieldbus controller 9251, which can be addressed with up to 8 measuring channels via a fieldbus interface and record and transmit the measured data, are used.
