DESCRIPTION
This all solid-state relay utilizes the
latest technology to provide a low ON
resistance. The control (input) and load
(output) are optically isolated to protect
input logic circuits from voltage and
current transients which can occur on
the output supply. The optical isolation
also provides a full floating output, thus
allowing the load to be connected to
either output terminal. The control circuit
is buffered to enable the relay to be
driven directly from standard CMOS or
open collector TTL logic circuits.
Available options include short circuit
and current overload protection, which
provides complete protection for both
the relay and the 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. In either case, the relay will
sense the short circuit condition and
then block it indefinitely until the short is
removed and the unit is reset by cycling
the input control. The second option is a
status output, which provides a built-in-
test function. This feature checks the
input circuitry of the relay and provides a
logic (0) low when the input circuit is
turned on and operational. Both options
are
separately as standard features.
