Universal Field/Head
Mounted Transmitter |
The SC-4400 transmitter has been
designed to minimize purchase and
installation costs through its universal
inputs and compact size. Accepting
thermocouple, RTD, mV, voltage, and
resistance inputs, the SC-4400
becomes a universal transmitter which
reduces spare parts inventory and
training/familiarization costs. Its
compact design and light weight allows
it to be installed in the sensor head
thereby reducing installation costs, and
simplifying engineering and documen-tation.
The unit is configured via Hand Held
Configurator, or a PC. Both allow a
permanent storage of the program for
fast duplication/downloading, and
through a connection to a printer, a
hardcopy of the program configuration
can be generated. The use of the
configurators with built-in prompts
eliminates the need for field adjust-ments
or errors, and reduces configu-ration
time.
The use of encapsulated circuitry and a
patented cover plate ensures excellent
temperature stability and RFI rejection
plus a typical .1% accuracy. They also
enable the units to be installed in
hazardous locations without the need
for explosion-proof housings.
Its unique design requires only 10 Volts
for operation, thereby enabling it to
drive into a 700 ohm load with a 24
Volt supply. Input-output isolation is
standard. |
Output
Load Regulation:
Between minimum and maximum
supply voltage the output will change
by <0.005% per volt.
Output Ripple:
<0.05% of span rms
Response Time:
For a step change in input, the output
signal will rise to within 1% of its final
value in < 1.5 seconds.
Sensor Failure:
TC Sensors & mV inputs - Software
selectable Upscale or Downscale for
open circuit sensor.
RTD Sensor - Software selectable
Upscale or Downscale for open circuit
sensor, Downscale for short circuit
sensor.
Under Upscale/Downscale conditions
the output will rise to 22 mA ±5% or
below 3.8mA respectively.
