DESCRIPTION
The Series KD and LD solid-state relays
are screened utilizing MIL-PRF-28750
test methods and are packaged in low
profile hermetically sealed cases. These
relays are constructed with state-of-the-
art solid state techniques and feature
fully
technology. This allows the load to be
connected to either output terminal and
provides a low ON resistance. The input
(control) and output are optically isolated
to protect input logic circuits from output
transients. Available options include
short circuit and current overload
protection, which provides complete
protection for both the relay and system
wiring. This feature not only provides
protection should a short or overload
occur while the relay is on, but will also
provide protection should the relay be
switched into a short. The second option
is a status output line. Switch status
returns the true status of the output
switch and is optically isolated from the
load. It provides status indication
independent of the control circuit of the
relay. The status line provides a logic 0
(low) when the relay output is off with
load voltage and continuity present, and
a logic 1 (high) when the output is on.
