SPTPS02 ABB Turbine Protection Slave Module

Product Description

The ABB SPTPS02, also cataloged as the SPTPS02 Turbine Protection Slave Module, processes turbine protection signals within ABB Symphony Plus and Infi 90 systems. It accepts magnetic pickup signals for overspeed monitoring, eddy-current probe signals for thrust wear monitoring, and temperature inputs from thermocouples, RTDs, or mA transmitters. Additionally, the module supports analog valve position inputs and 4-20 mA analog outputs.

Hardware Specifications

Turbine Protection Signal Processing

The SPTPS02 handles multiple signal types associated with turbine monitoring and protection. Its three magnetic pickup inputs support overspeed signal acquisition, while two eddy-current probe inputs support thrust wear monitoring. Temperature measurement uses eight configurable input channels for thermocouples, RTDs, or mA signals.

Furthermore, eight isolated 16-bit analog input channels support analog measurement tasks. The module also accepts a 4-20 mA valve position signal and provides two 4-20 mA analog outputs. Eight 24 VDC digital inputs support discrete signal acquisition.

The available specifications do not identify individual channel assignments, input ranges for each sensor type, output load limits, or protection trip thresholds. Verify these details against the applicable ABB hardware documentation before configuring protection logic.

Frequently Asked Questions (FAQ)

Q: Which sensor types does the SPTPS02 support for turbine monitoring?

A: The supplied specifications identify magnetic pickups for overspeed monitoring, eddy-current probes for thrust wear monitoring, and thermocouples, RTDs, or mA signals for temperature measurement.

Q: What power supply does the SPTPS02 require?

A: The specified supply is 24 VDC with a tolerance of +/-20%. The stated power consumption is 6 VA.

Q: Can the SPTPS02 interface with analog and digital field signals?

A: Yes. The supplied specifications list eight isolated 16-bit analog inputs, eight 24 VDC digital inputs, and two 4-20 mA analog outputs. A 4-20 mA input is also specified for valve position.

Field Installation Guidelines

• System compatibility: Confirm that the module matches the installed Symphony Plus or Infi 90 system configuration and the applicable rack or mounting arrangement.
• Power connection: Verify supply polarity and confirm that the 24 VDC supply remains within the specified tolerance before energizing the module.
• Signal wiring: Separate low-level sensor wiring from high-current power conductors to reduce electrical interference.
• Shielding and grounding: Follow ABB installation documentation for cable shielding, grounding points, and separation of signal commons.
• Sensor configuration: Verify magnetic pickup, eddy-current probe, thermocouple, RTD, and mA transmitter requirements against the actual channel configuration.
• Analog outputs: Confirm the connected receiver's input type and load requirements before connecting the 4-20 mA outputs.
• Commissioning: Check field wiring, signal polarity, channel readings, and diagnostic indications before enabling turbine protection functions.
• Environmental limits: Maintain rack air temperature between -25 and +70 deg C and relative humidity between 5 and 95%, non-condensing.
