Kubler SK 1A-1S1D2RS is a universal converter for analog input signals from ±10 V or 0/4 ... 20 mA. This module converts analog signals in a digital format (frequency, position or angular position). The output format can be an incremental signal or an absolute value in SSI format. In addition, the result of the conversion can be read via a serial RS232 or RS485 interface or via a USB port. The module can be easily and conveniently mounted in a cabinet on a standard DIN rail.
