STI300
Product Introduction
The ALSTOM STI300 is a shaft-speed measurement module used in industrial measurement and control systems. In the ALSPA Series 6 architecture, it operates as the I/O board in the MFC3000 controller rack, receiving signals from speed sensors and providing measurement information to the controller. The module also supplies power to connected measurement sensors.
The board has three measurement channels and front-panel connections for external wiring. Its condition and channel status should be checked through the MFC3000 device-status interface. Exact sensor compatibility, electrical input ranges, and supply characteristics should be confirmed against the installed board revision and system documentation rather than assumed from the STI300 designation alone.
Application Scenarios & Field Pitfalls
Typical applications
- Turbine speed monitoring: Measures shaft rotational speed for turbine control and monitoring systems.
- Industrial rotating equipment: Provides speed-sensor measurements for supported machinery monitoring and control applications.
- ALSPA Series 6 control systems: Serves as the measurement I/O board in MFC3000 rack configurations.
- Multi-channel speed acquisition: Uses three measurement channels for supported sensor inputs.
Field checks before replacement
- Confirm the system identity. Verify that the installed unit belongs to an ALSTOM system. is not a unique model designation across all industries.
- Check all three channels. Record the wiring and configured sensor assignments for CH1, CH2, and CH3 before removing the original board.
- Verify sensor compatibility. Confirm sensor type, supply requirements, signal characteristics, and configured measurement thresholds. Do not assume every speed pickup is compatible.
- Inspect the controller slot. The manual specifies the I/O board position in the rack. Do not relocate it based only on physical fit.
- Review diagnostic status. Check initialization, power, channel indicators, and online measurement values before returning the machine to service.
- Validate speed readings. Compare the replacement board’s readings against an independent reference before enabling speed-dependent control or protection functions.

Procurement and Replacement Notes
When sourcing an , request photographs of the complete board, front-panel connectors, identification label, and PCB revision. Also confirm that the target system is an ALSTOM and record its rack configuration.
A replacement should be checked against the original sensor wiring, channel configuration, and controller diagnostics. Do not use the EPEVER inverter specifications when evaluating the ALSTOM measurement board; they describe an unrelated product.
