TRI-SEN TURBOSAFE 1000048-001 Triplicated Electronic Overspeed Trip Device

The TRI-SEN TURBOSAFE 1000048-001

Technical Specifications

Purpose:
Designed to replace a traditional mechanical trip bolt on steam or gas turbines, power turbines, and other rotating equipment. It provides reliable overspeed trip protection for rotating equipment using magnetic speed sensors to determine rotational speed.

Features:

• 2003 (two-out-of-three voting) logic: Meets and exceeds the functional requirements of API 670 (Section 8.4).
• Easy on-line calibration and test: Each trip setpoint and speed measurement circuit can be calibrated and tested online using an external calibration source.
• Total response time ≤ 40msec: This is the elapsed time from overspeed detection, through decision-making logic, to initiating the trip signal (output).
• Wide speed range: 100 to 25,000-RPM, allowing the TurboSafe to protect virtually any turbomachinery train.
• Redundant power supplies: Accepts one or two external 24 VDC power sources.
• Accuracy: To 0.02% of speed, the highest measurement accuracy available for overspeed protection.
• Peak-hold: On highest detected speed stored for event analysis.
• Enclosure: Available in both a panel mount and a NEMA 4X enclosure.
• Outputs: Two independent Form-C trip relay outputs.
• Alarms: Three Form-C alarm relay outputs for each speed unit.
• Communications: Modbus (slave) RS485 Serial Communications.
