Historical Replacement
According to the ABB SPASI23 Analog Input Module User Manual (Document No. 2VAA001604), SPASI23 is documented as a replacement for SPASI03 and SPASI13. The manual also documents its relationship with IMASI23 for INFI 90 systems.
SPASI23 is used to acquire temperature, millivolt, and voltage signals in Harmony-based control systems.
Common maintenance scenarios include input signal faults, incorrect readings, configuration issues, and module replacement. The ABB manual includes troubleshooting and replacement procedures.
Before installation, verify the module address, jumper settings, I/O expander-bus dipshunts, and termination-unit configuration.
For SPASI03/SPASI13 replacement, check the required resolution settings and power-supply capacity before commissioning.
The ABB manual covers troubleshooting, preventive maintenance, module inspection, repair, replacement, and installation checks.
Maintenance should be performed by qualified personnel following applicable system safety procedures.
NTAI06 is the documented analog input termination unit associated with the ASI/SPASI analog input module, providing field signal termination for the 16 input channels.
The installation documentation also covers the associated cable and termination arrangements used with the module.
Note: These models are listed as available inventory only and are not official or compatible replacement models for SPASI23.
