These positive-switching 8-Channel Digital Input terminals acquire binary control signals from the process level and transmit them to the higher-level automation system. The eight channels indicate their signal state by means of LEDs. Using single-ended connections, these units are particularly useful for saving space in control cabinets. Power contacts are looped through, and the reference ground is the 0 V power contact.
