The EL6685-0010 serves as a high-precision reference clock for the distributed clocks system. For applications with the highest demands on time measurement, the built-in oscillator significantly increases the basic accuracy of the timer.
The EL6685-0010 offers significantly increased basic accuracy in the ppb range and enables the oscillator to be trimmed to an external reference clock. This enables a high hold-over time even if the external time signal is temporarily lost (e.g. by the EL6689 via GNSS or the EL6688 via PTP).
