Output range: 3.68 to 20.8 mA
HART
®
protocol is superimposed on the 4
to 20 mA signal. Any single value among
followings can be selected as the analog
output signal.
Sensor 1, Terminal Temperature.
Dual input type, same as above plus;
Sensor 2, Average, and Differential
Temperature.
Also, up to three of the above values can
be displayed on LCD display or read via
communication.
Fieldbus communication Type
Output signal based on FOUNDATION
eldbus
TM
communication protocol.
Isolation
Input/Output/GND isolated to 500V DC
Except lightning protector option.
Manual Test Output Function
The output value can be set manually.
Sensor Burnout (HART Type)
High (21.6 mA DC) or Low (3.6 mA DC), user
selectable.
Output in Transmitter Failure (HART Type)
Down-scale: –5%, 3.2 mA DC or less , sensor
burnout –2.5%, 3.6 mA (Optional code C1)
Down-scale: –5%, 3.2 mA DC or less (Optional
code C2)
Up-scale: 110%, 21.6 mA DC or more
(Standard or Optional code C3)
Update Time (HART Type)
Approximately 0.5 seconds for a single sensor
(0.8 second for dual sensors) at damping time 0
Turn-on Time (HART Type)
Approximately 6 seconds for a single sensor (7
seconds for dual sensors)
Damping Time Constant
Selectable from 0 to 100 seconds
Self-Diagnostics
Self-diagnostic function based on the NAMUR
NE107 standard detects failures in the
hardware, conguration and communications.
