SSI encoder interface; safe analog input, 2 channels; 125 kHz; binary code. The terminal provides an SSI interface for the direct connection of an SSI encoder. The terminal outputs a clock signal for reading the encoder and makes the incoming data stream available to the controller as a data word in the process image. Different operating modes, transmission frequencies, and bit widths can be set at the factory via control registers. The power supply for the encoder can be directly tapped at the terminal.
