POWER DISTRIBUTION ARCHITECTURE

The SIE uses two independent 24 VDC power

sources to operate. One set of dual redundant power

supplies provides logic power to the I/O chassis and

another set of dual power supplies provides power to

the field instruments. This redundant power

architecture provides protection against a single power failure.
