Datalogger for relay interlockings and level crossings

The SA380 logo

The SA380 is our signalling datalogger for relay-based interlockings. These devices precisely capture sequences of digital events, taking the uncertainty out of investigating faults or operational incidents.

Captured events are transmitted to our Centrix analysis platform, enabling graphical playback, customised alarms, and cross-checking with data from other MPEC products

SA-380c system

The SA380 is also dual purpose. It's the natural solution for judicial event recording and logging of relay actions. You can read more about this here.

With over 3,000 SA380 units installed across the UK, we have unparalleled experience and understanding of event logging requirements.

The SA380 has successfully been in service for over 15 years, delivering reliable and accurate data for our customers. This system remains fully supported by our in-house embedded development team, and continues to be relevant and resilient.
