EL2502 BECKHOFF PLC模塊
The EL2502 output terminal modulates the pulse width of a binary signal and outputs it electrically isolated from the E-bus. The mark/space ratio is prescribed by a 16 bit value
The output stage is protected against overload and short-circuit. The EtherCAT Terminal has two channels that indicate their signal state via LEDs. The LEDs are driven in time with the outputs, and show the mark/space ratio by their brightness.

盡管 Echo Hill 已經通過實施基于 EtherCAT 的控制平臺優化了機床的 生產能力，但成本沒有任何增加。“恰恰相反，”Dan Schellenberg 說 道：“由于機器人運動學軟件在*工業 PC 上運行，我們能夠降 低控制系統的總成本。此外，我們能夠顯著降低控制柜中的空間要 求、機床的占地面積和系統復雜性
