Signal Converters
-
On one hand, there are signal converters which transform an input frequency range into an analog signal. These signal converters are very easy to program and control. Other signal converters can transform analog input signals into analog normalized signals with galvanic insulation. Due to the fact that these signal converters can be freely graduated, they offer endless possibilities and 110 combinations can be selected by means of a DIP switch. Other kinds of signal converters can be connected to devices with RS-232, RS-485 or RS-422 protocols.
