External Timing Module

1. Time Service Interface: USB
2. Time Source: LTE-4G, BeiDou; the three time sources can switch between each other if one fails, ensuring time accuracy
3. Time Service Accuracy: LTE-4G time source accuracy is 20ms; GPS/BeiDou time service accuracy is 10μs
4. BeiDou receiving channels: 6; receiving sensitivity: -157.6dBW; cold start time: 15 seconds; hot start time: 1.5 seconds
5. Time Service Antenna: LTE-4G optional 100cm, 150cm
BeiDou optional 30 meters, 40 meters, 50 meters, 100 meters, 200 meters, 300 meters
6. Anti-interference: The device does not malfunction under lightning overvoltage, primary circuit operations, switchyard faults, secondary circuit operations, or other strong interferences. The device quickly releases the influence of interference sources.
7. Mean Time Between Failures (MTBF) >310,000 hours; service life >20 years; no maintenance required under normal use.
8. Supports Linux and Windows operating systems
9. Operating Voltage: DC12V and DC3.3V; Current: 150mA
10. Operating Temperature: 0~70℃
11. Relative Humidity: <90% non-condensing
12. Board Dimensions: 150x65x4mm
