The TXDIN101 is a computerized,
PC programmable, galvanically
isolated two-wire smart transmitter.
The unit converts 13 types of
thermocouple sensors; 12 types
of RTD sensors, configured as
2-, 3- and 4-wires; potentiometer,
resistor and millivolt inputs, single
or differential—into process current
loop. Integral 3% digits LED
display forms a transmitter—monitor
unit which is visiable in dark
installations. The light intensity varies as a function of the current loop, which serves as the light energy source
24-bit A/D converter
and two microprocessors are
the heart of the outstanding
performance. The transmitter
can be set and wired to perform
differential measurement
conversions of temperature sensors
as well as mV sources. The output
current is temperature linearized
and can be set to be 4 to 20/20 to
4mA—or any range within these
limits. The current is limited to
3.9 and 22 mA.The TXDIN101
samples and updates the output
current in a rate of 2 to 4 samples
per second depends on the sensor
type. The transmitter is fully
configurable in dry-configuration
mode by which the connection to
PC is performed with no external
power source. The configuration
parameters are stored in a nonvolatile
memory. Exceptional digital
accuracy of typically ±0.1°C is
provided for most sensors
regardless of the calibrated span.
Internal Pt-100 temperature sensor
provides precise cold junction
compensation throughout the entire
ambient range. Detection of sensor
breakage or disconnection of input
leads, forces the output to a predefined
up/down scale value.
The unit continuously monitors the
sensor and automatically returns to
normal operation mode when the
sensor is recovered. The TXDIN101
is housed in a plastic enclosure
mounted on a standard DIN rail.
Special red filter is provided for
optimal view.
