Description
The T713 series has 6 widely
adjustable input ranges and
2 output ranges, all of which
are field selectable via top
accessed DIP switches. The T713
provides 600VDC of isolation
with outputs of either 4-20mA
or 10-50mA. Current outputs
are linear to tempera- ture.
Urethane coating of internal
circuitry for protection from
corrosive atmospheres is included
as standard.
The
T713 has an 80% zero and span
adjustability within any user
selected input range. For example,
Range 1 of Table 1 specifies
0 to 1000 F with a minimum span
of 200 F (1000 - 200 = 800 ,
or 80%). This 80% adjustability
allows the user to field calibrate
the unit for the maximum (0
to 1000 ) down to any minimum
(200 ) span (e.g. 740 to 940
) - as long as that adjusted
span remains within the selected
0 to 1000 F range. The same
is true for any user selectable
range: all spans are field adjustable
from 20% (minimum span) to 100%
of the specified range.

Application
The T713 is useful in any application
requiring isolation of a 2-wire
loop current from a 3-wire RTD.
Typical applications include
SCADA and remote data acquisition
such as monitoring boiler or
custody transfer/pipeline temperatures.
The output of the T713 can be
used to drive a digital meter
for direct display or interface
with a computer for monitoring
and control applications.
The
T713 is FM approved for intrinsically
safe operation in Class I, Division
1, Groups A, B, C, and D; Nonincendive
Class I Division 2, Groups A,
B, C and D, and Classes II &
III, Division 2, Group G hazardous
locations when installed per
manufacturer's drawing 790-0024-00.
