The CT2100-400 is a quad solid
state relay. The device has been
designed to provide an interface
which
computer I/O port. The switches
are controlled by a single data
word which the processor writes to
an
addition
function ON/OFF and Trip flags
provide the operational status of
each of the four switches. These
signals are internally contained in
an 8 bit status register which is
accessible
command. The switches may also
be
(without write strobes) by use of
separate initialization pins. These
may also be used for Power-Up
control in a microprocessor based
system.

to parallel devices or place them
in series as required for the
specific application. Control of
the switch is via I/O write
(Address 0) or asynchronous
control lines. The CT2100-400
has an internal switch control
latch which is updated via

Each switch in the CT2100-400
is monitored for circuit Trip and
ON/OFF. This data is contained
in a 8 bit status register which is
accessible via an I/O read
(Address 0)
timing for the I/O read is shown
in Figure 1. The Trip and
ON/OFF flags are provided to
the
operational capability of the
switch versus the status of the
controlled load. The Trip bit is
set high when the switch has
conducted between 1.1 to 3
amps of current based on the
time to trip curve in Figure 3.
The over current DC trip point is
typically 1.3 amps.
