Digital switching system STS

for integration19" rackdata acquisition

STS is a state-of-the-art seismic switch / trip system packaged as a 19’’ rack module consisting of Slot-in Modules (SiMs) inserted into vertical slots with a remote accelerometer connected to it. It provides a set of highly reliable alarm contacts as outputs activated by exceedance of acceleration and/or based on state of health. The STS combines the best of the analog and digital technologies by utilising only hardware for the highly reliable alarms, and digital data acquisition for realtime digital monitoring, recording, playback, in-depth processing and archiving of the sensor signal. The unit provides full traceability of the sensor signal as well as the system logs—even if no trip was activated—with a buffer spanning to several weeks back. All of the digital information can also be provided to remote users in real time, on demand, continuously and/or periodically. Applications include: Automatic Seismic Trip System (ASTS) Detectors for integration in an ASTS Connection to an emergency shutdown system Nuclear Reactor protection Power Plant protection / stop Industrial Process protection / stop
