Product Description:
The EL6688 is an accuracy terminal which is specifically designed to be used as a reference clock within EtherCAT networks and can be fully utilized in TwinCAT systems. It provides distributed clocks as well as synchronous exact network devices through the application of the PTP protocol using both IEEE 1588-2002 (PTPv1) and IEEE 1588-2008 (PTPv2).
The terminal will provide uniformity and stability in timing among various components such that it proves to be efficient in those applications requiring coordinated accuracy. Being around 75 grams, the EL6688 is both lightweight and compact but meets high-strength performance. EMC compliant according to EN 61000-6-2 and EN 61000-6-4 standards, it provides high immunity and low emissions for noisy industrial spaces. Side-by-side installation is simplified with a double slot and key link, providing clean alignment with near terminals in modular I/O designs. The mechanical stability and convenience of installation are improved with the structural integration. The wiring is based on innovative push-in termination technology that allows for fast tool-free termination as well as safe electrical contact. The technology is also capable of minimizing the wiring error risk as well as ease maintenance.
The terminal has hardware diagnostics built-in, including status LEDs that offer instant visual feedback on operating states, faults, and synchronization status. Real-time feedback is necessary for system validation and troubleshooting while the system operates. With distributed clock capability, the EL6688 is the hub of systems where strict time synchronization is critical, including measurement, motion applications, and distributed control systems. With its function as a reference clock in TwinCAT, its flexibility is further enhanced by allowing the use of integrators to continue to have centralized control of time-critical functions. The EL6688 terminal enhances network timing performance without sacrificing compatibility with advanced automation platforms and harsh field environments.
