EL3068 Beckhoff High-performance 8-channel Analog Input EtherCAT Terminal Block
EL3068 Beckhoff High-performance 8-channel Analog Input EtherCAT Terminal Block
The Beckhoff EL3068 is a high-density, high-performance 8-channel universal analog input terminal in the EtherCAT I/O system, engineered for precise and flexible acquisition of voltage and current signals from a wide range of industrial sensors and transmitters. Supporting ±10 V, 0–10 V, and 0–20 mA (including 4–20 mA) on each channel—individually configurable—the EL3068 delivers 16-bit resolution, integrated diagnostics, and seamless TwinCAT integration in an ultra-compact 12 mm wide housing. This makes it ideal for space-constrained applications requiring maximum I/O density without compromising accuracy or reliability.
