Beckhoff EP1809-0021 EtherCAT Box is a 16-channel digital input module that accepts 24 V DC sensor signals and transmits them to an EtherCAT controller with galvanic isolation. It provides 16 digital inputs at 24 V DC (-15%/+20%) and an input filter of 3 ms, delivering debouncing for electronic and mechanical signals. The sensors are powered from the box supply voltage U_S, and the module uses M8 signaling connections for compact installation. As part of Beckhoff's EtherCAT Box family, the EP1809-0021 delivers robust, isolated digital inputs suitable for industrial automation and machine-control applications.
