SER-32e
Sequence of Events Recorder
The SER-32e Sequence of Events Recorder (SER) provides high-speed monitoring and event recording with 1 millisecond accuracy, helping organizations quickly identify the root cause of power system disturbances and operational events. Designed for critical power applications, the SER-32e monitors up to 48 digital inputs and records state changes with precise time synchronization using PTP, IRIG-B, DCF77, and NTP protocols.
An embedded secure web server enables setup, monitoring, diagnostics, and event retrieval through a standard web browser with no proprietary software required. The large 4.3-inch color touchscreen simplifies configuration and real-time status monitoring, while seamless integration with EPMS, SCADA, Building Management Systems (BMS), and Data Center Infrastructure Management (DCIM) platforms provides valuable operational visibility.
With expandable I/O modules, advanced time synchronization capabilities, and greater than 10 seconds of control power ride-through, the SER-32e helps improve power system reliability, accelerate troubleshooting, and reduce downtime across mission-critical facilities.
The SER-32e replaces the SER-3200 and SER-2408, which are no longer available.
Features
- Millisecond Event Recording – Captures and records state changes with 1 ms timestamp accuracy across up to 48 digital inputs, enabling accurate event reconstruction and root-cause analysis.
- Flexible Time Synchronization – Supports PTP (IEEE 1588-2019), NTP, IRIG-B, DCF77, and legacy inter-device synchronization for precise, system-wide event correlation.
- Browser-Based Configuration – Embedded HTTPS web server provides setup, monitoring, diagnostics, and event management through a standard web browser with no proprietary software required.
- Intuitive Touchscreen Interface – Large 4.3-inch color touchscreen simplifies device setup, diagnostics, event review, communication status, and real-time input monitoring.
- Seamless System Integration – Integrates with EPMS, SCADA, BMS, and DCIM platforms using Modbus TCP, Secure Modbus TCP, RESTful API, SNMP, and Ethernet networking.
- Built-In Cybersecurity – Secure browser access through HTTPS encryption and support for Secure Modbus TCP helps protect device communications and configuration data.
- Expandable Architecture – Two expansion slots support optional digital input and relay output modules, allowing customization for evolving application requirements.
- Control Power Ride-Through – Integrated Power Control Module provides greater than 10 seconds of ride-through, helping ensure critical events are captured during power interruptions.
- Trigger Output for Waveform Capture – High-speed trigger output enables event-driven waveform capture and deeper system analysis when paired with compatible monitoring devices.
- Event Data Export – Export event records directly to Excel for commissioning, troubleshooting, reporting, and operational analysis.
