The Beckhoff EL1809 is a high-density EtherCAT Terminal designed for acquiring 16 channels of 24 V DC binary control signals from the process level and transmitting them in electrically isolated form to higher-level automation units. This compact module features a 12 mm housing width with 16 connection points, offering exceptional space savings in control cabinets. Each channel includes individual LED status indicators and a 3 ms input filter to eliminate mechanical switch bounce and ensure reliable signal processing. The terminal supports tool-free direct plug-in wiring for solid conductors and 1-wire connection technology, making it ideal for connecting multi-channel sensors with minimal wiring. The EL1809 conforms to EN 61131-2 Type 1/3 specifications and provides 500 V electrical isolation between E-bus and field potentials, ensuring robust performance in demanding industrial automation applications.
