Designed for the most critical control programs, supervised digital output (SDO) modules meet the needs of systems whose outputs remain in a single state for extended periods of time (in some applications, for years). An SDO module receives output signals from the main processors on each of three channels.
Each set of three signals is then voted upon by a fully faulttolerant quadruplicated output switch whose elements are power transistors, so that one voted output signal is passed to the field termination.
The 3625 Invensys Triconex Digital Output Modules may still be available for purchase and support from Moore Automated Company beyond End-Of-Life (EOL) by the manufacturer (OEM).

The modules are called “supervised” because fault coverage is extended to include potential field problems. In other words, the field circuit is supervised by the SDO module so that the following field faults can be detected:
• Loss of power or blown fuse
• Open or missing load
• A field short resulting in the load being energized in error
• A shorted load in the de-energized state
Failure to detect field voltage on any output point energizes the power alarm indicator. Failure to detect the presence of a load energizes the load alarm indicator. All SDO modules support hot-spare modules and require a separate external termination panel (ETP) with a cable interface to the Tricon backplane.
