Description
The GE ALSTOM SCN804C is a Measure Interface Module used in legacy Alstom / GE Power Conversion industrial control systems. It functions as a measurement and interface board for transferring measurement-related signals within the control architecture. Available technical references identify the SCN804C as a PLC module / measure interface board and specify two power supplies, a 28-position terminal block, and a 25-pin D-Sub connector. The module is associated with the SCN804 family and is suitable as a replacement component where the existing system requires the same hardware configuration.

The SCN804C should be replaced by matching the complete board identification, connector layout, power-supply arrangement, and host-system configuration. The SCN804 family contains related but distinct revisions, including SCN804, SCN804C, SCN804D, and SCN804E, so the revision should not be assumed interchangeable without verification.
