The SK-PC-D2-UU1-10-HS is an open-type USB barrier that provides two
USB channel connections. The barrier is intended for installation into an
ATEX/IECEx certified, tool-removable, IP54 minimum enclosure and is
suitable for installation in Zone 2, Group IIC hazardous locations. The
barrier provides "ic" energy-limited field wiring to Zone 2, Group IIC and
Zone 22, Group IIIB hazardous locations.
For each of the two USB channels, the barrier provides four lines to the "ic"
intrinsically safe apparatus: The power lines (V+, GND) and the data lines
The SK-PC-D2-UU1-10-HS may be mounted in Class I, Div. 2, A, B, C, D
and Zone 2, IIC locations. The barrier provides non-incendive outputs for
Class I, Div 2., A, B, C, D; Class II, Div. 2, F and G; Class III, Div. 2; Zone
2, IIC; and Zone 22, IIIB areas based on the entity parameter concept.
