Product Short Description
Technical Specifications
- Redundancy Architecture: Triple Modular Redundant (TMR) with hardware-based fault tolerance.
- Input Channels: Three independent channels for speed signal acquisition (supports proximity probes, magnetic pickups, or encoder inputs).
- Speed Range: 0–100,000 RPM (configurable based on application requirements).
- Accuracy: ±0.1% of full-scale reading.
- Response Time: <10 ms for fault detection and signal output.
- Output Signals:
- Three isolated relay outputs for alarm or trip signals.
- 4–20 mA analog output for speed trending (optional).
Description
- Communication: Supports Modbus RTU/TCP or Profibus DP for integration with control systems.
- Power Supply: 24 VDC (18–32 VDC operating range).
- Environmental Rating:
- Operating Temperature: -20°C to +70°C.
- Storage Temperature: -40°C to +85°C.
- Humidity: 5–95% non-condensing.
- Certifications: IEC 61508 SIL 3, TÜV, UL, and CE compliant.
Functional Features
- Triple Redundancy: Each channel operates independently, ensuring continuous monitoring even if one channel fails.
- Online Diagnostics: Real-time self-diagnostics to detect sensor faults, signal loss, or internal module errors.
- Hot Swapping: Supports replacement without system shutdown, minimizing downtime.
- High Vibration Resistance: Designed to withstand harsh industrial environments with vibration levels up to 5G.
- Programmable Alarms: User-configurable speed thresholds for under-speed, over-speed, and rate-of-change alarms.
- SOE Recording: Sequence of Events (SOE) logging with 1 ms resolution for post-incident analysis.
- Isolation: Galvanic isolation between input, output, and power circuits to prevent noise interference.
