OMEGA™ Solid State
Relays and Zener
Barriers for
Intrinsic Safety
The maximum energy
possible at the switch
terminals of the OMEGA™
zener barriers is far below the
explosive point of the most
volatile surrounding gas
conditions. The type of
non-voltage-producing
switch or sensor best
fitted for the application
can be used, since
the entire switching
circuit is rendered
intrinsically safe by the
OMEGA™ zener barrier.
Because the switching
circuit is low voltage, there
is no shock hazard to
operating or maintenance
personnel.
Installation
and Maintenance
OMEGA™ zener barrier
units are normally
installed in a safe area
and connected to the
sensor in a hazardous location;
no explosion-proof or protective
housings are needed. Units install
singly in any position, or can be
grouped on a common earthgrounded
plate with mounting tabs
to provide electrical grounding.
Between 6 and 32 threaded
electrical terminals are conveniently
placed atop the unit housings.
