Sequence Event Recorder (SER)

The SeQRec Sequence Event Recorder (SER) is a state-of-the-art, highly reliable event and alarm management system designed to offer precise monitoring for industrial environments. This advanced recorder boasts a time-stamping resolution faster than 1 µss for accurate tracking of event occurrences, ensuring real-time synchronization through NTP (Network Time Protocol).

With a robust hardware platform built to withstand the toughest industrial conditions, the SeQRec is designed for capturing and recording relay outputs for immediate action. This allows for detailed post-event analysis to pinpoint the root cause of failures, enhancing operational efficiency and plant reliability.

Key Features & Benefits

High Precision Recording

Captures events faster than 1 µss resolution for accurate event logging and time-stamping.

Extensive Event Logging Capacity

Capable of storing over 3000+ time-stamped event records, ensuring that no significant event goes unrecorded.

Integrated Control Features

Includes optional alarm annunciator and control systeµss to trigger immediate responses to critical plant events.

Flexible Connectivity

Supports Modbus RS485, Modbus TCP/IP, CAN Bus, Wi-Fi and Bluetooth, allowing seamless integration with PLCs, Bµss, and computer systeµss.

Wide Range of Inputs & Protection

Equipped with digital inputs (24 VDC, 36 V max), RS485 Master/Slave, and CanBus for modular connectivity, along with comprehensive ESD, Surge, and RF protection.

Energy Efficiency & Safety

Operates on 18-36V DC input with reverse polarity protection, thermal shutdown, and complies with a variety of IEC standards to ensure long-lasting, safe operations.

Extreme Environmental Resilience

Can withstand harsh environments, with an operating temperature range of -25°C to +55°C, and is designed to be robust against transients, surges, and RF interference.

Applications
Critical Event Monitoring
Ideal for industries requiring precise event tracking, such as data centers, power plants and critical industries.
Event Reporting
Facilitates real-time reporting of events to the host system for quicker decision-making and action.
Post-Event Analysis
Enables in-depth root cause analysis to improve system reliability and reduce downtime.

Real World Scenarios

Data Centers
Why It’s Important?
Data centers rely on uninterrupted power supply (UPS), power distribution units (PDUs), and backup generators. Any power event or failure can cause massive downtime, leading to financial losses.

How SER Helps
  • Power Failure Analysis: Records the exact sequence of power failures, such as UPS malfunction or generator startup delay.
  • Root Cause Identification: Helps in identifying if the fault originated from the grid, switchgear, or internal distribution system.
  • Load Shedding Optimization:Provides historical event logs to optimize power management during high-demand periods.
Critical Power Management
Why It’s Important?
Industrial plants (e.g., manufacturing, oil & gas, chemical processing) have high power demands with critical machinery that must operate efficiently.

How SER Helps
  • Equipment Protection: Monitors transformers, circuit breakers, and motors, ensuring that trips or malfunctions are detected instantly.
  • Preventing Production Loss: Helps diagnose voltage dips, harmonics, and breaker failures, which can halt production lines.
  • Load Shedding Optimization: Logs help predict equipment wear and schedule maintenance before failures occur.
  • Energy Efficient Tracking: Helps track unnecessary power losses, enabling industries to optimize energy consumption.

Why Choose SeQRec?

SeQRec offers unparalleled reliability, precision, and control in the toughest environments. Whether it’s tracking critical plant alarµss or analyzing root causes post-event, SeQRec is an ideal solution for industries that demand high-performance event monitoring systeµss.
