SHAKE SS300 is an advanced seismic switch with a tri-axial MEMS accelerometer to help with earthquake disaster mitigation. The unit has three sets of fully isolated mechanical relays. Using Modbus RTU communication, the device can be connected to other systems to activate emergency processes in the event of an earthquake. Equipped with a 100 dB MEMS accelerometer and flash to store the last earthquake information, SHAKE SS300 two sets of DI inputs make set-up and use simple.

The sampling rate of SHAKE SS300 is fixed at 200 SPS to ensure accurate data. Along with the low-pass filter, artificial vibration noise can be effectively filtered out. The dynamic offset allows SHAKE SS300 to be installed on the ground or wall. The three sets of relay can be activated through different settings, such as PGA, PGV and seismic intensity scales, including MMI, KMA, JMA, GBT, and CWB standards. Users can also monitor, test or reset relays through Modbus RTU.
