SER-3200/SER-2408

Sequence of Events Recorder

The Sequence of Events Recorder (SER-3200 / SER-2408) provides precise, 1 ms event time-stamping across up to 32 channels, enabling accurate root-cause analysis and system diagnostics. With versatile time synchronization—PTP, IRIG-B, DCF77, NTP, and inter-device RS-485—the SER ensures accurate coordination across critical systems. Integrated Ethernet with Modbus TCP, RESTful API, embedded  web server, and FTP access allow seamless integration with SCADA and power monitoring platforms. Built for reliability with non-volatile memory and solid-state relay outputs, the SER is ideal for utilities, data centers, and industrial operations requiring accurate and compliant event logging.

Features

  • High-Resolution Event Logging – Records events on up to 32 channels with 1 ms accuracy, ensuring precise sequence capture for diagnostics.
  • Reliable Data Storage – Non-volatile memory with SDHC card support up to 32 GB preserves event history even during outages.
  • Versatile Time Synchronization – Supports multiple time sources including PTP, IRIG-B, DCF77, NTP, and inter-device RS-485 for system-wide accuracy.
  • Time Distribution Outputs – Provides IRIG-B, DCF77, ASCII, and PTP outputs to synchronize downstream devices.
  • Flexible Integration – Ethernet connectivity with Modbus TCP,  web server, RESTful API support, and FTP ensures seamless SCADA and monitoring system integration.
  • Control & Trigger Functions – Solid-state relay outputs and high-speed trigger output enable system control and waveform capture with compatible power meters.
  • Durable & Industrial-Grade – Wide operating temperature range (-25ºC to +70ºC), DIN rail mounting, and rugged solid-state design ensure reliability in demanding environments.
  • Certified & Compliant – UL-61010, UL-508, CSA, CE, RCM, FCC Class A, and RoHS compliance  ensure safety, quality, and environmental responsibility.
