SEIKO QC-5500 Series is a high-precision quartz master clock. By connecting with an external master clock generating 30-sec polarized signal output, time correction can be made. Models operating on AC 110 V (QC-55X01) and AC 220 V (QC-55X02) are available.
(1) Master clock function (QC-5510X, QC-5520X and QC-5530X)
Up to 30 secondary clocks can be connected to each channel (if the current consumption of each secondary clock is 12 mA).
(2) External synchronization function
By connecting with an external master clock generating 30-sec polarized signal output, the loss/gain of the clock is corrected automatically.
