Theory of Operation
The SRO Module is a non-triplicated module for use on non-critical points which
are not compatible with high-side, solid-state output switches; for example,
interfacing with annunciator panels.
Logic Power
Each module is designed to operate directly from redundant 24 volts DC power
sources as shown on
. Logic power is carried baseplate-to-baseplate,
allowing a single logic power connection per column. The power conditioning
circuitry is protected against over-voltage, over-temperature, and over-load
conditions. Integral diagnostic circuitry checks for out-of-range voltages and over-
temperature conditions. A short on a channel disables the power regulator rather
than affecting the power sources.
