INTRODUCTION
The
SEM523P
is
a
dual
channel
DIN
rail
temperature
transmitter
which
accepts
common
RTD
sensors
and
converts
them
into
a
4
to
20
mA
linear
output.
Since
Zero
and
Span
are
set
to
conform
to
a
particular
sensor
type,
the
sensor
temperature
co-efficient
(0.00385,
0.00392
etc.)
has
little
to
no
effect
on
accuracy.
The
simple
push
of
a
button
ranges
and
calibrates
the
SEM523P
transmitter.
There
is
no
need
for
jumpers,
potentiometer
adjustments
or
a
computer.
Ease
of
re-ranging
assures
you
will
have
the
range
you
need
in
stock.
High
accuracy,
stability,
and
flexibility
at
a
very
attractive
price
make
the
SEM523P
the
transmitter
of
choice
for
many
applications.
The
SEM523P
provides
a
level
of
performance
superior
to
analog
units
at
comparable
price.
CALIBRATION
PROCEDURE:
- Connect
an
RTD
simulator/calibrator
to
the
input
and
between
8
&
30
volts
DC
to
the
output
of
the
SEM203P.
- Set
the
simulator
to
the
desired
temperature
at
4
mA.
Press
and
HOLD
the
calibration
button
until
the
LED
starts
to
blink.
- Set
the
simulator
to
the
desired
temperature
at
20
mA.
Press
the
calibration
button
and
release.
The
LED
continues
blinking
and
then
shuts
off
confirming
that
the
unit
is
calibrated.
It's
that
simple
and
that
fast.
