Electrical Data
• When combined with Trapezoidal and Rectangular
output characteristic FISCO model IIC barrier
Ui = 17.5 V, Ii = 380 mA, Pi = 5.32 W,
Ci = 3.52 nF, Li = 0 μH
• When combined with Linear characteristic barrier
Ui = 24 V, Ii = 250 mA, Pi = 1.2 W,
Ci = 3.52 nF, Li = 0 μH
• When combined with Trapezoidal or Rectangular
output characteristic FISCO model IIB barrier
Ui = 17.5 V, Ii = 460 mA, Pi = 5.32 W,
Ci = 3.52 nF, Li = 0 μH
Note 3. Installation
• All wiring shall comply with local installation
requirements. (Refer to the installation diagram)
Note 4. Maintenance and Repair
• The instrument modification or parts replacement
by other than authorized representative of
Yokogawa Electric Corporation is prohibited and
will void DEKRA Intrinsically safe Certification.
Note 5. Special Conditions for Safe Use
WARNING
• In the case where the enclosure of the Pressure
Transmitter is made of aluminium, if it is mounted
in an area where the use of category 1 G
apparatus is required, it must be installed such,
that even in the event of rare incidents, ignition
sources due to impact and friction sparks are
excluded.
• Electrostatic charge may cause an explosion
hazard. Avoid any actions that cause the
generation of electrostatic charge, such as rubbing
with a dry cloth on coating face of the product.
• In the case where the enclosure of the Pressure
Transmitter is made of aluminum, if it is mounted in
an area where the use of category 2D apparatus is
required, it shall be installed in such a way that the
risk from electrostatic discharges and propagating
brush discharges caused by rapid flow of dust is
avoided.
• To satisfy IP66 or IP67, apply waterproof glands to
the electrical connection port.
• When the lightning protector option is specified,
the apparatus is not capable of withstanding the
500V insulation test required by EN60079-11.
This must be taken into account when installing
the apparatus.

SUPPLY
• In the rating 1(*1), the output current of the barrier
must be limited by a resistor ‘Ra’ such that Io = Uo/
Ra.
• In the rating 2(*2), the output of the barrier must be
the characteristics of the trapezoid or the rectangle
and this transmitter can be connected to Fieldbus
equipment which are in according to the FISCO
model.
• The terminators may be built in by a barrier.
• More than one transmitter may be connected to
the power supply line.
• The terminator and the safety barrier shall be
certified.
