The Beckhoff EL1104-0000 is a robust EtherCAT Terminal designed for acquiring binary control signals within an industrial automation environment. This 4-channel digital input terminal processes signals from the process level and transmits them, with electrical isolation, to the central automation unit. It is specifically designed for 24 V DC signals and incorporates a 3.0 ms input filter to ensure signal stability and prevent noise. The status of each input is clearly indicated by an integrated LED, simplifying diagnostics and system monitoring during operation.
