SERᴺᴱᵀ Sequence of Events Recorder
Brand: RIS - Scientific ColumbusEach SERᴺᴱᵀ product can work as a stand-alone system monitoring up to 48 digital inputs or multiple SERᴺᴱᵀ units can be networked together to form a larger system with all events consolidated in one chronological list as they occur.
A single WEB browser screen can display alarms from several SERᴺᴱᵀ units, making it easy to see the interaction between different equipment types or processes.
This flexibility makes it easy to analyze alarms across an entire site or even across multiple sites for a larger system view - much better than piecing together a list of alarms from multiple devices.
Features- Capture alarms to 1 msec precision across entire system
- IEC-61850 compliant
- 40,000 event storage per unit
- WEB browser configuration and display of alarms
- Network multiple units together for "big picture" view
- Time sync via IRIG-B and NTP
- Modbus, DNP, ASCII, BACnet protocols
- LED indicator per alarm
- Email notification
- Meets new NERC SER requirements
- 19" rack and surface mounting
