GS5227 1PPS 10MHz Redundant Switching Distributor

The GS5227 Redundant Switching Distributor is a multi reference backup time synchronization terminal. It supports seamless switching among three 10MHz and 1PPS inputs, and offers both manual and automatic operation modes. In automatic mode, if any of the three input signals fails or is interrupted, the system performs a full switch to an alternate reference. In manual mode, users can select any valid input as the reference for switching. Regardless of the mode, the device continuously outputs 10MHz, 1PPS signals, and NTP time information. Critical to its design is the requirement that the 10MHz and 1PPS signals switch simultaneously to the corresponding input channel.

The GS5227 features multiple 10MHz and 1PPS outputs, and is additionally capable of operating as an NTP network time server. The device's key advantages are its seamless switching and dual-redundant design: seamless switching ensures phase continuity without jumps before and after the transition, while dual-redundant power supplies significantly improve system reliability.

Additionally, the GS5227 can function as a distributor. When a reference source is selected, the input signal can be directly distributed to multiple outputs, making it a high-performance device that integrates distribution, switching, and time synchronization functions.

Application areas

 

 

Time and frequency metering stations at all levels;

Users requiring time/frequency signal testing and distribution;

Timing systems;

Signal switching and distribution for the ground inspection system;

Timing systems, monitoring stations, master control stations, and related fields.

• It features two 10MHz sine wave signal inputs and can switch and distribute 16 frequency standard signals to the output; (three inputs are optional);
• It features two 1PPS second signal inputs and can switch and distribute outputs to 12 second pulse signals; (3 inputs are optional);
• It features two serial port time inputs and device status information inputs, and monitors the status of the input source in real time to provide a time source for NTP time synchronization;
• Features dual AC power inputs and operates as a dual power time server, significantly improving system reliability.;
• It features manual and automatic reference source switching, allowing users to set the switching method and select a reliable reference source according to their needs;
• The output signal can be selected as local output or reference source output. If local output is selected, a seamless switching mechanism is activated, which can ensure that the signal is continuous and does not jump during the switching process. If reference source output is selected, the distributor function is activated, which directly distributes the input signal into multiple outputs;
• It has the function of remote monitoring, reporting the status of the device and external input signals in real time. At the same time, it provides a control protocol, allowing users to remotely set device parameters via serial port;
• It features a clock setting function (date, time, time zone, leap second, etc.); users can set any time;
• It has an indicator light function, which can indicate the status of input and output signals in real time, and will give an alarm status once an abnormality is detected;
• It features an LCD display that can show the time, current reference source, input signal status, and output signal status in real time, and also has a log query function.
