The barriers feature a bused power feed and offer both relay and
solid-state switch models. They provide removable terminals within a
space-saving design—with channels as small as 6.3mm wide—to consume
minimal panel space. Each channel is fitted with two stages of
pulse-tested diodes and an infallible terminating resistor, says the
vendor. If an electrical fault such as an overvoltage occurs in the
non-hazardous area of the barrier, the diodes limit the voltage
available to hazardous area circuits, while the series resistance
limits the current. Within this circuit is a fuse designed to
immediately and safely rupture if the excess energy continuously
applied to the barrier exceeds the design criteria for the loop.
