DESCRIPTION
The Model 9210 Diode Input Card is
designed
to
be
installed
in
a
DRC-91C
or
DRC-93C
to
convert
either the Input A or Input B (or
both
with
two
options)
t o
accommodate diode sensors with a
voltage output of up to 3.0000
volts (9210-3 configuration)
,
The
9210-3
is
used with
Lake Shore
DT-500-DRC
or
DT-470
Series
Sensors.
Calibrated
DT-500
or
DT-470
Series
Sensors
can
be
accommodated with an
8000
Series
Precision Option.
The
9210-6
configuration will
accommodate diode sensors (TG-120
series) with voltages between
0
and
6.5535 volts.
A calibrated sensor
and
8001
Precision
Option
is
required for the DRC-91C/93C
to
read
accurately
in
temperature.
9210-3 can be converted to 9210-6
configuration by switch on the 9210
Diode Input Option Card.
This
configuration will also read DT-470
and DT-500 series sensors but with
reduced resolution and accuracy.
See Table 9210-1,
9210.3 SPECIFICATIONS
Specifications for the Model 9210
Diode Input Card are given in Table
9210-1. The card
can
be configured
by the user as either a
3
volt
(9210-3) or a
6
volt (9210-6) card.
Sensor
(ordered
separately):
DT-470 series, MI-500 series
and TG-120 series from LSCI as
well as any other diode sensor.
See Lake Shore Diode Sensor
brochures.

on Diode Sensor. See Sensor
brochure.
