Features:
- Provides the Basic I/O Interface for GEM80/141 and GEM80/142.
- Carries the controller-to-I/O data path in the supported rack arrangement.
- Uses the exact 8172-4003 assembly configuration.
The 8172-4003 identity comes from the original GEC GEM80 140-series hardware literature.
It links the controller architecture with the Basic I/O structure used by the installed system.
Record slot and connector relationships before service because the interface affects more than one I/O module.
Availability is confirmed against the complete 8172-4003 identity, required condition, quantity and delivery destination at quotation.

- Connect Basic I/O hardware to a GEM80/141 programmable controller.
- Maintain the I/O data path of a GEM80/142 legacy automation rack.
- Restore a failed 140-series interface during planned plant maintenance.
- The module fits the Basic I/O position documented for the 140-series rack.
- Processor and I/O connectors must follow the original rack layout.
- Adjacent module order should remain unchanged during interface replacement.
- Use is documented with GEM80/141 and GEM80/142 controllers.
- The connected I/O structure must be the supported Basic I/O arrangement.
- Later GEM80 families require an explicit interface mapping rather than an assumed fit.
- The board carries the parallel system I/O data path through its rack connectors.
- Cable orientation and retention determine reliable communication with connected I/O.
- Inspect contact condition before attributing intermittent data loss to logic hardware.
