ALSTOM  IR139-1 Product Overview

Electrical Specifications

1.Power Supply: 24 VDC (±10% tolerance)

2.Power Consumption: ≤5.0 W

3.Input: 2 independent magnetic pickup (MPU) speed sensor channels; 0–10,000 RPM measurement range (configurable)

4.Output: 4 SPDT relay outputs (2 safety trip outputs with force-guided contacts)

5.Isolation Voltage: 1,500 VDC (channel-to-ground)

6.Operating Temperature: 0°C to +60°C

7.Protection Rating: IP20 (rack mount)

8.Safety Certifications: API 670, IEC 61508 SIL2

Main Functions

1.Overspeed Monitoring: Continuously measures shaft speed via dual MPU sensors and detects overspeed conditions.

2.Emergency Trip Protection: Triggers safety relays to shut down machinery when overspeed exceeds configurable thresholds.

3.Redundant Signal Validation: Compares data from two independent channels to confirm fault conditions and avoid false alarms.

4.Self-Diagnostics: Built-in self-test circuitry monitors module health and sensor connectivity for early fault detection.

5.System Integration: Seamlessly integrates with ALSTOM 3300/50 rack systems and connects to ETS/SIS for plant-wide safety.

Application Cases

1.Power Generation: Deployed in thermal power plants to protect steam turbines, gas turbines, and generators from overspeed failures.

2.Oil & Gas: Used in refineries and offshore platforms for overspeed protection of large compressors and turbo-machinery.

3.Petrochemical Industry: Applied in chemical plants to safeguard high-speed rotating equipment (e.g., centrifuges, blowers).

4.Heavy Industry: Integrated into steel mills and processing plants for protection of large steam-driven rotating assets.

5.Industrial Turbines: Utilized in independent power producers (IPPs) and cogeneration plants for turbine safety protection

Key Features

1.Dual-Channel Redundancy: Two independent speed monitoring channels eliminate single-point failures for high safety integrity.

2.Fail-Safe Design: Only trips when both channels confirm an overspeed event, preventing false trips and ensuring reliable protection.

3.Wide Speed Measurement Range: Configurable 0–10,000 RPM range adapts to various rotating machinery types.

4.Safety Relay Outputs: 2 force-guided contact relays for direct emergency trip (ETS) integration.

5.Compliance with Industry Standards: Meets API 670 and IEC 61508 SIL2 requirements for machinery protection.

6.Rugged Industrial Construction: Operates reliably in 0°C to +60°C environments for power and petrochemical applications.
