Nowadays various types of data transmission and interfaces are used in processes. Nearly every process includes a control system that receives data either by means of analog signals or by data transmission. The data is then evaluated and the appropriate parameters are set.
A reliable process control essentially depends on the faultless, untroubled and secure transmission and processing of these analog signals. There may however, arise numerous problems which can disturb or even block an ideal process sequence.
ABB’s range of analog signal converters are ideally suited when existing electrical or physical values have to be converted into proportional standard signals or relay threshold signals.
The serial data converters from ABB allow the establishment of a communication between units with different communication standards.
In order to assure the process continuity, existing systems consistently have to be updated or connected to new devices. If the communication standard of the existing system and the connected device are different, serial data converters make the establishment of the communication possible.
Besides the conversion of signals, analog signal converters and serial data converters are suited for the amplification, filtering or separation of analog signals.
