Beckhoff EL1819 is an EtherCAT Terminal that provides 16 digital input channels for 24 V DC signals, with a 10 µs input filter to suppress noise and debounce state changes in industrial environments. All inputs share a common ground via the 0 V power contact, and the module presents a 16-bit input image on the EtherCAT process data, making it a high-density option for digital sensing in automation systems. The EL1819 uses Beckhoff's 1-Wire input connection technology for straightforward wiring of sensors or switches and is designed for use with EtherCAT masters in factory automation where fast, synchronized digital inputs are required.
