The AED9401A and AED9501A weighing electronics from HBM enable digitization without any loss of information up to the physical noise limit, enabling certification as Class III weighing machines with the maximum permissible number of 10,000 divisions. The performance of the two devices has been confirmed by independent tests issued by an independent notified body.
Both devices allow strain gauge (SG) transducers to be digitally connected to standard fieldbus systems using either CANopen or DeviceNet interfaces. The electronics can be fully PC-controlled and provide integrated, electrically isolated control inputs and outputs ensuring that they can be used for both static and dynamic measurements.
The AED9401A/9501A offers a crucial advantage for plant engineering and automation companies seeking to install a customer-specified bus system for export. The CANopen protocol is preferred in Europe while DeviceNet systems are widespread in the American and Asian markets. With the AED9401A/9501A both CANopen and DeviceNet can be used as interfaces, depending on the specification, with changeover via a software command.
