“I thought we could get by with basic metering and NTP time sync, but then we had an incident. The CyTime SER-3200 gave us the data to reconstruct why our transfer scheme switched over to generator power. Now I specify all SER devices with 1ms accuracy.“
CyTime SER-3200/2408 Sequence of Events Recorder (SER) provide 1 ms event recording for up to 32 channels. These devices enable root-cause analysis of complex power systems—now using Precision Time Protocol (PTP) for hi-res time-sync over Ethernet.

Sequence of Events Recorder (SER)
Know what happened and when—to 1 millisecond! CyTime Sequence of Events Recorder models SER-3200/SER-2408 record status changes of up to 32 channels, time-stamped to 1 ms. Time synchronization is achieved via PTP (IEEE 1588), IRIG-B, DCF77, NTP, Modbus TCP or an RS-485 signal from another SER. An embedded web server allows setup over a network using a standard browser, plus easy access to all events, status and even custom pages you create (or we’ll do them for you).
CyTime Sequence of Events Recorder is the first to use PTP to achieve “hi-res” time synchronization over Ethernet for commercial/industrial applications. One CyTime SER serves as PTP master and all other CyTime SER devices sync automatically within 100 microseconds—without special Ethernet switches. Since most relays or meters don’t yet support PTP, an SER-3200/2408 also serves as the time-sync master for these devices, generating the legacy protocol (IRIG-B, DCF77, etc) required. This eliminates the redundant cabling between equipment lineups normally needed for 1ms timing.
The CyTime Sequence of Events Recorder enables accurate event recording in modern data center Electrical Power Monitoring Systems (EPMS). [ More ]
Emergency Power Supply Systems (EPSS) in hospitals use the CyTime Sequence of Events Recorder in automatic test and reporting systems to ensure reliable backup power and document compliance with testing regulations. [ More ]
Power SCADA for Process Industries
The SER-3200/SER-2408 Sequence of Events Recorder offers precision event recording for supervisory control and data acquisition systems in continuous processes such as refineries and water treatment plants. [ More ]
Microgrids and Alternative Energy
The CyTime Sequence of Events Recorder provides critical data for root-cause analysis in microgrids and alternative energy networks, such as wind, solar and fuel cells. When used with compatible power monitors or protective relays, the SER-3200/SER-2408 trigger waveform captures coincident with events, for advanced diagnostics and preventive maintenance. [ More ]
Reliable operation. Dedicated event-processor captures cascading events reliably—zero-blind-time—independent of network traffic or other demands on processor bandwidth (unlike some relays, meters, and PLCs).
Know breaker opening times. The SER-3200/2408 records the exact time of the initiating event (e.g., relay trip) and resulting state (tripped) to calculate breaker opening times under different load conditions. [ See Tech Note for details ]
Hi-res (1-ms) time-sync over Ethernet via PTP. Just set the first SER time, all other SER’s sync automatically using PTP (IEEE 1588).
Simple setup. An embedded web server hosts intuitive web pages to facilitate setup and monitoring—no software to install.
Advanced troubleshooting. Trigger output to command a compatible power meter to capture current and voltage waveforms coincident with an event.

Markets & Applicatioins
“We needed to automate the EPSS testing required by the AHJ. The CyTime SER-2408 monitors status of all our ATS and makes our testing faster and more efficient.”
"I have legacy devices that use RS-485 4-wire communications, but I need to connect these to a 2-wire network. The CNV-100 from Cyber Sciences is simple—it just works!"
“Microgrids combining utility sources, wind and solar power are complex by design. The requirement for SER with 1 ms accuracy is a given."
