Easy way to connect strain gauge devices to fieldbus networks

By using fieldbus technologies, the need for an on-site control cabinet is eliminated, and the system can also assume some PLC control tasks. The system is supplied with integrated, electrically isolated control inputs and outputs and can be used for both static and dynamic applications.

The fully computer-controlled AED system aids plant efficiency because fieldbus interfaces cover longer distances, while the industry-standard housing is installed close to the application to provide a high degree of protection.

All common interfaces are supported, including: the latest generation of Profibus DP V1, CANopen and DeviceNet, as well as RS 232, RS 422, and RS 485.

The AED system uses an 18-30V supply and includes different digital filters, sampling rate adaptation, works and user characteristics, and linearisation. Over 100 structured commands provide access to the strain-gauge transducer or system. Specialised features include smart optimisation functions and control functions required for repetitive processes - for example, in automatic scales. Service, development, start-up, and parameterisation software are also available.
