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).

AI3281 Data sheet
|
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.
|
|
Each SDO module has voltage and current loopback circuitry coupled with sophisticated online diagnostics that verify the operation of each output switch, the field circuit and the presence of a load.
|
|
An SDO module receives output signals from the main processors on each of three channels.
