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