Output“◊”
For 4 to 20 mA output
(Output signal code D, E and J)
Two wire 4 to 20 mA DC output with digital
communications, linear or square root
programmable. BRAIN or HART FSK protocol
are superimposed on the 4 to 20 mA signal.
Output range: 3.6 mA to 21.6 mA
Output limits conform to NAMUR NE43 can be
pre-set by option C2 or C3.
For 1 to 5 V output
(Output signal code Q)
Three or four wire low power 1 to 5 V DC output
with HART, linear or square root programmable.
HART protocol is superimposed on the 1 to 5 V
DC signal.
Output range: 0.9 V to 5.4 V DC
FailureAlarm“◊”
For 4 to 20 mA output
(Output signal code D, E and J)
Analog output status at CPU failure and
hardware error;
Up-scale: 110%, 21.6 mA DC or more
(standard)
Down-scale: –5%, 3.2 mA DC or less
For 1 to 5 V output
(Output signal code Q)
Analog output status at CPU failure and
hardware error;
Up-scale: 110%, 5.4 V DC or more
(standard)
Down-scale:−5%,0.8VDCorless
Damping Time Constant (1st order)
Amplierdampingtimeconstantisadjustable
from 0 to 100.00 seconds and added to
response time.
Note: ForBRAINprotocoltype,whenamplierdamping
is set to less than 0.5 seconds, communication
may occasionally be unavailable during the
operation, especially while output changes
dynamically. The default setting of damping
ensures stable communication.
UpdatePeriod“◊”
45 ms
Zero Adjustment Limits
Zero can be fully elevated or suppressed, within
the lower and upper range limits of the capsule.
ExternalZeroAdjustment“◊”
External Zero is continuously adjustable with
0.01% incremental resolution of span. Re-range
can be done locally using the digital indicator
with range-setting switch.
Integral Indicator (LCD display)
5-digit Numerical Display, 6-digit Unit Display
and Bar graph.
Theindicatoriscongurabletodisplayoneor
up to four of the following variables periodically.;
Pressure in %, Scaled pressure, pressure in
Engineering unit.
