Beckhoff Terminal, 8-Channel Analog Input - EL3068
The EL3068 EtherCAT Terminal features eight channels for processing voltage signals within the 0 to 10 V range. Each channel digitizes voltage inputs with a resolution of 12 bits and transmits them in an electrically isolated manner to the higher-level automation system. This terminal consolidates all eight channels into a single housing, with power contacts routed accordingly. The 0 V power contact serves as the reference ground connection for all inputs, ensuring consistent signal integrity.

Information About EL3068
The EL3068 EtherCAT Terminal is designed for processing analog signals within a voltage range of 0 to 10 V. Each of its eight channels operates in a single-ended configuration, digitizing input voltages with a high-resolution of 12 bits. This ensures precise measurement and transmission of analog data to the connected higher-level automation system, all while maintaining electrical isolation.
Physically consolidated into a single housing, the EL3068 integrates power contacts that facilitate efficient signal transmission. The terminal utilizes the 0 V power contact as the reference ground connection for its inputs, ensuring consistent and reliable signal processing across all channels. Operational status and signal activity are visually indicated by integrated light emitting diodes (LEDs), enhancing monitoring capabilities during deployment and operation.
Key specifications include a maximum internal resistance of over 130 kΩ, ensuring minimal interference and robust signal integrity. The terminal incorporates an input filter with a limit frequency of 1 kHz, supporting effective noise reduction and signal stability in industrial environments. It offers a conversion time of 1.25 ms as a default setting, configurable for multiplex operation to suit varied application requirements.
