Information About EL4008

The EL4008 is an EtherCAT Terminal designed to generate analog output signals within the range of 0 to 10 V. This terminal integrates eight output channels within a single housing, offering efficient space utilization. The voltage output to the process level is provided with a 12-bit resolution, ensuring precise signal generation. Electrical isolation is maintained between the E-bus and the signal voltage, with an isolation voltage rating of 500 V. 

Each output channel of the EL4008 shares a common ground potential. The output stages derive power from a 24 V DC supply via power contacts. The terminal is equipped with distributed clocks, enabling high synchronization precision with a precision rating significantly less than 1 µs. The typical load capacity is greater than 5 , and the outputs are designed to be short-circuit proof. 

The conversion time for the EL4008 is approximately 400 µs, facilitating rapid signal processing. In terms of current consumption, the power contacts typically draw 40 mA, while the E-bus consumes around 100 mA. The bit width in the process image is structured as 8 x 16-bit analog output.
