Universal and galvanic isolation
A major advantage of ProfiMessage devices is that its inputs and outputs are differential, high-precision and galvanically isolated – from each other and from the power supply. Earth loops and non-isolated sensors therefore present no problems. This unique system architecture prevents earth loop distortions and enables the problem-free measurement of non-isolated signals.
Depending on the I/O module, each input can be individually configured for measuring mV, mA, RTD and thermocouples. Universal inputs for voltage, current and temperature measurement make ProfiMessage devices extremely flexible. Digital inputs are also available as status or frequency inputs along with digital and analog outputs.
Data storage functions
The integrated data memory can be partitioned and triggered to enable users to save their data either continuously or according to specified events. A drag&drop option makes it easy to assign connected channels to storage/memory groups. In the same way users can save data from virtual channels - i.e. channels that extend the functionality of data acquisition systems.
The ProfiSignal software is used for both manual and automatic data memory read out. Partial and full data transfers from the data logger's memory can also be performed using a USB stick.
Redundant storage within the device means data is secure even in the event of a PC or network failure; data security is important, and not just for FDA21 CFR Part11 compliance.
