SER-32e
Sequence of Events Recorder
The ER-32e Sequence of Events Recorder delivers high-speed, millisecond-accurate event recording across 32 channels, enabling root-cause analysis and advanced diagnostics for critical power systems. With precise 1 ms time-stamping and support for multiple time synchronization protocols (PTP, IRIG-B, NTP, DCF77), it ensures system-wide accuracy. A large 4.3” color touchscreen simplifies setup, diagnostics, and input monitoring, while an embedded secure web server (HTTPS) eliminates the need for proprietary software. With expansion slots for added I/O, extended control power ride-through, and seamless integration into SCADA, power monitoring, and building management systems, the SER-32e enhances reliability, security, and operational insight.
Features
- Millisecond Precision – Monitors and records up to 48 channels with 1 ms resolution, enabling accurate root-cause analysis of critical events.
- Time Synchronization Flexibility – Supports multiple time protocols (PTP, NTP, IRIG-B, DCF77, Inter-SER), ensuring precise system-wide event correlation.
- User-Friendly Operation – Large 4.3” color touchscreen simplifies menu navigation, device setup, diagnostics, and real-time monitoring.
- Seamless Integration – Easily integrates into SCADA, Power Monitoring, and Building Management Systems with Modbus TCP and RESTful API.
- Built-In Cybersecurity – Embedded HTTPS web server with 256-bit encryption ensures secure configuration and data access.
- Resilient Performance – Extended control power ride-through guarantees critical events are captured even during power outages.
- Expandable Design – Two expansion slots add up to 16 extra I/O points, scaling capacity to evolving system needs.
- Advanced Diagnostics – High-speed trigger output to trigger waveforms captures via compatible power meters for deeper system insights.
