Product Introduction
The ABB 500TTM02 1MB150021R0116 is a legacy measurement/transducer module associated with ABB’s 500-series control and protection hardware. The exact identification 500TTM02 1MB150021R01161HF930712X010 is repeatedly indexed alongside the ABB 500-series modules used in protection and control architectures.
The available technical references describe the 500TTM02 as a transducer or measurement-oriented module. Its role is to condition measurement signals so that the associated control or protection processor can use them for monitoring, control logic, or protection calculations. A secondary technical reference specifically describes this exact part as a transducer module for signal conditioning, although it does not provide enough primary documentation to establish all electrical ratings.
The ABB 1MB150021R0116 and 1HF930712X010 identifiers should both be retained when sourcing a replacement. The 500-series includes several modules with similar naming conventions, and the complete part-number combination is more reliable than the generic 500TTM02 designation alone.

Main Features & Field Considerations
Measurement interface
The 500TTM02 is associated with measurement/transducer functions rather than ordinary binary I/O. It should therefore be evaluated according to the actual electrical signals connected to the module.
Legacy ABB architecture
The module belongs to an older ABB hardware ecosystem. ABB-related references place it alongside CPUs, communication modules, transformer-input modules, binary I/O modules, and system interface hardware.
Exact configuration matters
The following identifiers should be matched:
- 500TTM02
- 1MB150021R0116
- 1HF930712X010
Do not substitute another 500TTM02 solely because the front-panel designation is identical.
Replacement Checks
Before replacing an ABB 500TTM02, verify:
- Complete part number and additional marking
- Host ABB 500-series system
- Rack/slot position
- Connected measurement circuits
- Input signal type and range
- Output/interface signal
- Associated CPU and processing module
- Hardware revision
- Existing configuration/scaling parameters
- Wiring and terminal assignments
If the module handles current-transformer circuits, follow the site’s approved CT isolation and shorting procedure before disconnecting any wiring.
Important Specification Caution
There is conflicting information in secondary-market listings for the 500TTM02. One listing calls the part a binary input module and assigns generic relay/I/O specifications, while another describes the exact 1MB150021R01161HF930712X010 as a transducer module.
For that reason, I would not state a definitive input voltage, channel count, output current, communication protocol, or accuracy specification for this exact variant without the original ABB technical documentation. Those numbers are too likely to be copied from unrelated ABB modules.
Procurement Note
For ABB 500TTM02 1MB150021R0116 1HF930712X010, use the complete identification string when requesting a replacement. The exact combination is independently indexed within ABB 500-series documentation and parts references.
For a live installation, preserve the existing wiring, signal scaling, configuration parameters, and module revision information before replacement. The safest approach is an exact part-number match rather than substituting a different 500-series measurement or I/O module.
