The EL1889 is a digital input terminal designed for EtherCAT-based distributed I/O systems. It features 16 channels that acquire binary control signals operating at 24 V DC from the process level. The terminal transmits these signals in an electrically isolated form, ensuring reliable signal processing. It is configured for ground switching and supports one-wire connections, with a typical response time of approximately 3 milliseconds. The EL1889 takes its reference power contact from the 24 V power supply line, allowing for straightforward connection without tools in the case of solid conductors. This high-density input module provides efficient and secure digital input acquisition within industrial automation setups.
