Some converters also have a certain logic that can be used to determine what to do with signals that go beyond boundaries, trigger a relay or discrete signal to a certain level, set the input signal limits, etc. There are converters with a learning button that sets limits, Filters can be enabled so that the converter does not respond to rapidly changing processes. To handle these switches, you can use a touch-sensitive touch screen with buttons, which can be transmitted to the other inverter on top of it. It is possible to connect via Bluetooth.
