Output specications for HART Protocol Type “◊
Output
Dual output (Both analog and pulse/contact
output can be obtained simultaneously).
In this case refer to the item “Wiring example for
analog output and status/pulse output”.
HART Protocol Revision
HART protocol revision can be selected from 5
or 7 when ordering.
The protocol revision can be changed by user
conguration.
Note: Protocol revision supported by HART
conguration tool must be the same or higher
than that of the EJX multivariable transmitter.

Analog Output
Two wire 4 to 20 mA DC output, user-selectable
for Differential Pressure, Static Pressure,
External Temperature or Flow Rate signal.
Failure Alarm
Analog output status at CPU failure and
hardware error
Up-scale: 110%, 21.6 mA DC or more
(standard)
Down-scale: –2.5%, 3.6 mA DC or less
Analog output status at process abnormality
(Option code /DG6);
The result of process abnormality detected
by the advanced diagnostic function can
be reected to an analog alert status. The
following three setting modes are available.

Pulse/Contact Output
Pulse or status output is selected by parameter
setting.
Transistor contact output (sink type).
Contact rating:
10.5 to 30 V DC, 120 mA DC max.
Low level: 0 to 2 V DC. (See gure below for
high and low levels (pulse output).)

Pulse Output
Scaled pulse or frequency pulse output is
selected by parameter setting.
Scaled Pulse Output Function
Pulse is output by the unit of the scaled ow rate.
Scaled pulse can be totalized.
Frequency Output Function
Number of pulses output per second at 100% of
output.
Pulse frequency: Max. 10 kHz
Duty cycles: Approx. 50% (1:2 to 2:1)
Contact Output Function
High or low alarm
Status signal output mode can be reversed
(ON/OFF).
