Schedule
 
EQUIPMENT:
Equipment and systems covered by this certificate are as follows:
 

 

The isolator KFD2-RCI-Ex1 is an interface that converts a digital input signal (0-24 Volt) coming from a Safe Area to a digital current output signal (4-20 mA) to drive a solenoid valve placed in Hazardous Area. An auxiliary analog output (with fixed current of about 11 mA) is available towards the Safe Area which provides the possibility of a HART communication between the safe-area and haz-area. The module is powered at nominal 24 Vdc either with screw terminals or through the Power-Rail.

The ambient temperature may vary in a range of -20°C to + 60 °C.

 

 
CONDITIONS OF CERTIFICATION: NO

for gas Group IIC

Co      :      0.104μF          Lo    :    4.05mH            Lo/Ro    :     60μH/Ω

 

for gas Group IIB

for gas Group IIA

Co   :        2.82μF             Lo    :    32.4mH            Lo/Ro    :     480μH/Ω

 

The capacitance Co and either the inductance Lo or the inductance to resistance ratio (Lo/Ro) of circuits connected to the output terminals of the apparatus must not exceed the above values. 

Note: The above load parameters apply where:

-     the external circuit contains no combined lumped inductance Li  and capacitance Ci greater than 1% of the above values;

or

-   the inductance and capacitance are distributed as in a cable;

-    the external circuit contains either only lumped inductance Li or lumped capacitance Ci in combination with a cable.

In all other situations e.g. the external circuit contains combined lumped inductance Li and capacitance Ci, up to 50% of each of the L and C values is allowed.
