9. General Specifications
9.1 Standard Specifications
Refer to IM 01C25T02-01E for FOUNDATION
Fieldbus communication type and IM 01C25T04-
01EN for PROFIBUS PA communication type for
the items marked with “◊”.

Output “◊”
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.
Failure Alarm “◊”
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
Note: Applicable for Output signal code D and E
Damping Time Constant (1st order)
Amplifier damping time constant is adjustable
from 0 to 100.00 seconds and added to
response time.
Note: For BRAIN protocol type, when amplifier 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 “◊”
Differential Pressure: 45 ms
Static Pressure: 360 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 configurable to display one or
up to four of the following variables periodically.;
Differential pressure in %, Scaled Differential
pressure, Differential Pressure in Engineering
unit, Static Pressure in Engineering unit.
See “Setting When Shipped” for factory setting.
Burst Pressure Limits (Differential pressure

Ambient Temperature Limits
–40 to 85°C (–40 to 185°F)
–30 to 80°C (–22 to 176°F) with LCD display
Process Temperature Limits
–40 to 120°C (–40 to 248°F)
Ambient Humidity Limits
